drac@unaffiliated ~ $ xfce4-appfinder *** glibc detected *** free(): invalid next size (fast): 0x08087ca0 *** Aborted Output of strace, and compile: http://hideout.unk.fi/~drac/appfinder.txt I've tried with GCC 3.4.5, GCC 4.0.2 and GCC 4.1BETA. I've also tried with system, where binutils, glibc, gcc are compiled with GCC 4.0.2 and with Syetem where they are compiled with GCC 4.1BETA. Binutils is version 2.16.1 Glibc is version 2.3.6 I've reseted MAKEOPTS, and CFLAGS. Allthough, my CFLAGS is only -O2 -pipe -march=athlon-xp and nothing else. It's a SVN version from today. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Okay, it started when I run it with valgrind: http://hideout.unk.fi/~drac/appfinder2.txt
http://hideout.unk.fi/~drac/appfinder3.txt is output with --tool=memcheck It runned again, with valgrind..
After upgrading of GTK+ from 2.8.12 to 2.8.13, and upgrading Xfce4 from SVN, Cairo from CVS.. it just works. I don't know what fixed it.
