I made a wrapper script to find out more and waited for the next crash The pnmnorm is called as ppmnorm (which is a link to pnmnorm) from the vidwhacker xscreensaver program and sometimes it crashes. I have captured the input file causing the crash. Hope it helps. Version-Release number of selected component (if applicable): netpbm-progs-10.28-1.FC4.2 How reproducible: Always Steps to Reproduce: 1. pnmnorm < problem.ppm > output.rpm Actual Results: Floating point exception Expected Results: output.ppm file should have been written Additional info:
Created attachment 122719 [details] pnmnorm input file - gzipped This is the file triggering the crash. It is gzipped, the original file is over 2MB big.
The bug is caused by division by zero in the normalization function. I tested it with the latest upstream version we have in devel and it's fixed there (pnmnorm displays a warning). I'll close this after FC4 updates are released.
Fixed in CVS.
From User-Agent: XML-RPC netpbm-10.31-1.FC4 has been pushed for FC4, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
