Bug ID: 1308365
Summary: slic3r crashes when loading known good stl files
Product: Fedora
Version: 23
Component: slic3r
Assignee: mhroncok(a)redhat.com
Reporter: johnduchek(a)gmail.com
QA Contact: extras-qa(a)fedoraproject.org
CC: mhroncok(a)redhat.com,
perl-devel(a)lists.fedoraproject.org
Created attachment 1127097
--> https://bugzilla.redhat.com/attachment.cgi?id=1127097&action=edit
This is an stl file that slic3r is having trouble with. It is an sd card holder
Description of problem:
slic3r loads a known good stl file, announces that it is too large and was
automatically scaled down to fit your print bed, on saying 'ok' slic3r closes
completely.
The file is 'known good' as it loads into the slic3r in Fedora 22 with no
problem (not too large)
I ran from terminal with these results:
[jduchek@localhost ~]$ slic3r
Warning: File size doesn't match number of facets in the header
Caught C++ exception of unknown type at
/usr/share/perl5/vendor_perl/Slic3r/GUI/Plater.pm line 1791.
Version-Release number of selected component (if applicable):
1.2.9-3.fc23
How reproducible:
always on the files it decides are too large. Some files still load properly.
Steps to Reproduce:
1.Run slic3r
2.add affected file (stl)
3.say ok, when it tells you it has fixed the file.
Actual results: slic3r closes so you have to start over
Expected results: display the loaded file.
Additional info: I have attached an affected stl file

--- Comment #1 from Miro Hrončok <mhroncok(a)redhat.com> ---
I can reproduce this.
Netfabb basic says this is an invalid STL file.
ADMeshGUI silently loads the file but displays nothing.
ADMesh for command line produces the following output:
================= Results produced by ADMesh version 0.98.2
================
Input file : sd-organizer-style.stl
File type : Binary STL file
Header :
��������������������������������������������������������������������������������
============== Size ==============
Min X = -0.000000, Max X = 31139554425569280.000000
Min Y = -4.787809, Max Y = 216341.203125
Min Z = -0.000000, Max Z = 847403352064.000000
========= Facet Status ========== Original ============ Final ====
Number of facets : 608 664
Facets with 1 disconnected edge : 67 0
Facets with 2 disconnected edges : 36 0
Facets with 3 disconnected edges : 12 0
Total disconnected facets : 115 0
=== Processing Statistics === ===== Other Statistics =====
Number of parts : 27 Volume : 2236782408995176448.000000
Degenerate facets : 19
Edges fixed : 0
Facets removed : 31
Facets added : 87
Facets reversed : 761
Backwards edges : 0
hexdump of a normal binary STL file looks like:
0000000 4f43 4f4c 3d52 0000 0000 0000 0000 0000
0000010 0000 0000 0000 0000 0000 0000 0000 0000
*
0000050 f06c 0000 0000 0000 0000 0000 0000 bf80
...
First 80 bytes are header (null terminated). Next 4 bytes are number of facets.
hexdump of your file looks like:
0000000 ffff ffff ffff ffff ffff ffff ffff ffff
*
0000400 454d 4853 4d2d 5345 2d48 454d 4853 4d2d
...
As you can see a lot of first bytes are replaced with 0xFF. If your header is
not supposed to be nonprintable garbage and number of your facets isn't max of
UINT32, which the file size doesn't indicate, something is wrong with your
file.
Slic3r should not crash about it. I've tested with binary from slic3r.org and
also got crash (although the output in terminal is slightly different). Could
you please go and report this upstream, if you think Slic3r should display a
decent error message?

I passed all the information here to slic3r.org. I have found several files
that 'used to work' exhibiting this problem. I am at a loss to see how the
header could be garbage as I haven't changed them after downloading them. Must
of done something. Anyway, thank you for the analysis and suggestions.

--- Comment #4 from Fedora End Of Life <jkurik(a)fedoraproject.org> ---
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
of '23'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.
Thank you for reporting this bug and we are sorry it could not be fixed.
