Hello to all,
I have recently replaced F11 with F12 on my sheevaplug an I came across strange php error. Following php script:
<? echo 1/4; ?>
outputs 5.2894475160536E-315 instead of 0.25.
On F11 everything worked without problems.
Thank you for any suggestions an kind regards
Uros

outputs 5.2894475160536E-315 instead of 0.25.
I had noticed a few alignment problems while building the new php. Could you see if this is also because of this?
Could you please check if it works after enabling fixups. That is:
# echo 2 > /proc/cpu/alignment
And then check it out?
On F11 everything worked without problems.
Thank you for any suggestions an kind regards

Hi Kedar,
yes, that fixes the problem. Thank you.
How can I make this change permanent? By adding this line to /etc/rc.local?
Kind regards Uros

Yes sure. Although making this change will cause your system to be a bit slow.
The right thing to do would be to fix the bug in the php package.
Could you assist in further debugging by:
Option1: * echo 3 in /proc/cpu/alignment, this will dump core when the alignment error occurs, thus letting know where exactly did it happen.
Option2: * echo 1 in /proc/cpu/aligment, this will put messages in /var/log/messages pointing to where the alignment error might have occurred.
Kind regards Uros
Kedar.

Hi,
echo 1 > /proc/cpu/alignment
outputs 5.2894475160536E-315 and
Dec 11 02:48:32 sheeva kernel: Alignment trap: php (3172) PC=0x001a21f4 Instr=0xe1c700f0 Address=0x00406bd4 FSR 0x801
in /var/log/messages.
echo 3 > /proc/cpu/alignment
outputs correct result 0.25 and same output in /var/log/messages
Kind regards Uros
