--- Begin Message ---Package: libc6-i686 Version: 2.10.1-1 Severity: critical Justification: breaks unrelated software Hello, With the upgrade to 2.10.1, pthread_cond_wait() fails to re-acquire the provided mutex when acting on a deferred cancellation event from another thread. This is seen if (and apparently, only if) another thread acquires the same mutex after cancellation is initiated, but before the cancelled thread executes cancellation cleanup handlers. I could not reproduce the problem with plain libc6. It only occurs with libc6-i686 installed. I wrote a simple test case at: http://www.remlab.net/files/divers/condfail.c This is a violation of POSIX threads semantics, and a regression from earlier libc6-i686. This also renders VLC media player debug versions almost completely unusable.

[ Samuel Thibault ] * Add patches/hurd-i386/cvs-linkat.diff to fix new coreutils' ln. * Add patches/hurd-i386/submitted-ttyname.diff to fix io/tst-ttyname_r, marked as such in testsuite-checking/expected-results-i486-gnu-libc. * Restore patches/hurd-i386/submitted-getnprocs.diff which got lost during the 2.11 merge. . [ Aurelien Jarno ] * Add patches/i386/local-cpuid-level2.diff to not trigger an abort when an i586 Intel CPU is running the i686 library, as valgrind does. Closes: bug#584748. * mips testsuite: allow failure of tst-tls3 as it is not a regression. * Add patches/any/submitted-string2-strcmp.diff to fix warnings in the testsuite on armel. * Add patches/alpha/submitted-syscall.diff from Mike Hommey to add support for 6th argument system calls on alpha. Closes: bug#583911. * Temporarily add patches/i386/local-pthread_cond_wait.diff to use the C version of pthread_cond_wait() which uses cleanup functions to reacquire the mutex on cancellation (instead of unwinding for the assembly version).
