Bug 47183 – compiling with -ffast-math causes rhythmbox to segfault

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Flammie Pirinen (RETIRED) 2004-04-07 23:36:59 UTC]

I have two nearly similar gentoo boxes at home, one works as a server box and the other for multimedia and development. On multimedia box which uses aggressiveish c-flags by default the rhythmbox would have always segfaulted but on server box with almost no c-flags it worked. After testing with some dozen of different settings I think that at least ffast-math will always result in segfault on program launch. (I think this problem affects also number of other media programs.)

Reproducible: Always
Steps to Reproduce:
1. CFLAGS=-ffast-math emerge rhythmbox
2. launch rhythmbox
3.

Actual Results:  
Segmentation fault.

Expected Results:  
Program starting

what versions of rhythmbox is this true for?

[Comment 2 Jeremy Huddleston (RETIRED) 2004-04-12 00:22:34 UTC]

Could you please tell me which version of rhythmbox you noticed this problem with?

[Comment 3 Flammie Pirinen (RETIRED) 2004-04-15 08:49:14 UTC]

I apologize the delay, I was on easter vacation. Judging from portage's logs it seems it has affected at least versions 0.6.8 and 0.6.1. The versions of gcc were 3.3.3 and 3.3.1 respectively.
