Description Michael Johnson 2004-10-12 20:15:57 UTC 
install gstreamer-plugins with gcc 3.4
with the following flags
CFLAGS="-O -march=athlon-xp"
CXXFLAGS="-O -march=athlong-xp"

run gst-register

--

It seems to be a problem with the plugin gst/modplug
if gst/modplug is built with the flag "-fgcse" (or -O2 or higher)
everything seems to work.

I can't reproduce this.  You'll have to provide more information, such as a
stack trace.  I wouldn't be surprised if this is a gcc bug that has been fixed
(since I don't see it).
Comment 3 Christian Fredrik Kalager Schaller 2004-12-21 15:56:38 UTC 
Michael, we need an update from you. Setting to NEEDINFO for now.
Comment 4 Koop Mast 2004-12-21 21:05:02 UTC 
Michael asked me to generate a backtrace. So here it is.
I don't know much about debuggin but frame #8 looks suspicious.

Compile flags: -O -march=athlon-xp
Some more detailed gcc info:
gcc -v
Using built-in specs.
Configured with: FreeBSD/i386 system compiler
Thread model: posix
gcc version 3.4.2 [FreeBSD] 20040728

Taht's stack corruption. Can you compile fastmix.cpp without -march=athlon-xp?
It's probably a compiler bug.
