When running programs that are linked against /lib/libpthread.so.0, valgrind uses its compiled libpthread, which results always in: [some messages] error while loading shared libraries: libpthread.so.0: cannot enable executable stack as shared object requires: Invalid argument [many lines later] Segmentation fault Reproducible: Always Steps to Reproduce: 1. valgrind --tool=memcheck /bin/ls 2. 3.

Thought this one might interest you, Christian. And any additional information you may have on this would be appreciated.
interesting, yeah, but able to fix? well.... I gonna take a closer look tonight on it, too... thx ;)
ah, btw, you can workaround this by remerging glibc without nptlonly useflag! - so much for now, cya ;)
I added valgrind-2.2.0-r1 that includes a fix. If it doesn't fix the problem, please reopen this bug. Thanks for reporting the problem.
Excellent. Thanks a lot.

This is a completely different problem. Please open a separate bug report for it. Did this problem first occur with -r1? I doubt it.
