to get this backtrace I recompiled lmms with 

CFLAGS="-march=barcelona -O1 -pipe -ggdb"
CXXFLAGS="${CFLAGS}"
LDFLAGS="-Wl,-O1"
USE="${USE} debug"
FEATURES="${FEATURES} nostrip keeptemp keepwork splitdebug"

but the segfault happens with my usual setting as well (see emerge --info below)


Reproducible: Always

Steps to Reproduce:
Just run the app for a while.

As you can see, I didn't recompile qt-core with the debug USE flag. If you need debugging information from qt as well, just tell me and I will recompile qt and provide all necessary information.
Comment 1 Lars Wendler (Polynomial-C) (RETIRED) gentoo-dev 2009-01-12 01:41:35 UTC 
Reassigning proaudio herd, CCing maintainer.
Comment 2 Thomas Kuther 2009-02-28 23:20:35 UTC 
Sorry, never got the CC mail.

Does that still happen with 0.4.3?
Comment 3 Lars Wendler (Polynomial-C) (RETIRED) gentoo-dev 2009-03-04 03:32:30 UTC 
I currently don't have that machine I experienced this problem on anymore. I tried to reproduce the segfault on another ~amd64 machine I am using but cannot reproduce it with version 0.4.3 and the limited tests I did.
So I mark this bug as fixed.
