How to get a core dump from the koji buildsystem

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hallo, I have a very specific issue with gnu-smalltalk-3.0.1. When I try to build it on the koji buildsystem, I will get a segmentation fault. please see http://koji.fedoraproject.org/koji/getfile?taskID=427144&name=build.log I have notified the upstram aothor about this issue. Because he has asked for the core dump, want to ask, how I can get a core dump from the buildsystem. I was not able to reproduced this scenario on an other system. Best Regards: Jochen Schmitt
