I have upgraded the system to linux26-headers-2.6.6-r1 and glibc-2.3.4.20040619. Now some applications crash due to SIGSEGV - xmms, xine, ogg123, ... When I used valgrind I got the following report. $ valgrind --tool=memcheck xmms ==2760== Conditional jump or move depends on uninitialised value(s) ==2760== at 0x3C008EBA: (within /lib/ld-2.3.4.so) ==2760== by 0x3C001E29: (within /lib/ld-2.3.4.so) ==2760== by 0x3C00E9FF: (within /lib/ld-2.3.4.so) ==2760== by 0x3C000C5F: (within /lib/ld-2.3.4.so) xmms: symbol lookup error: /usr/lib/valgrind/libpthread.so.0: undefined symbol: __libc_sigaction btw.

Did you try to remerge those apps? I cannot say I had the same thing, but especially if you also now updated to use NPTL, it would be the cause.
Yes, I did. Sorry that I did not say that before. I performed the following actions. emerge unmerge linux-headers emerge --one-shot linux26-headers emerge glibc emerge gcc compile new kernel and module-init-tools emerge -Du system (yes, upgrade only) revdep-rebuild emerge xmms xine-lib xine-ui valgrind vorbis-tools These applications still fall. I do not know if there is an old version library on which these applications depends. I am going to try to remerge the whole system.
The problem has been "solved" by USE="-nptl" emerge glibc
closing... please reopen if you have any further issues or this exists in more recent glibc verisons.
