Package: libc6 Version: 2.21-0experimental0 Severity: normal Tags: upstream fixed-upstream Forwarded: https://sourceware.org/bugzilla/show_bug.cgi?id=18463
Hello, the attached program fails with an error on ARM platforms. (I only tested armhf, but I think armel is affected, too.) The problem is that pthread_mutex_unlock() in the main thread returns EPERM which it shouldn't. This only happens when using pthread_cond_broadcast, at least two threads and PTHREAD_PRIO_INHERIT. For more details refer to the upstream bug[1]. A possible solution documented in the upstream bug report is to pass --enable-kernel=3.15 (or something bigger). According to https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=armhf&ver=2.21-0experimental0&stamp=1426842906 glibc is build using --enable-kernel=2.6.32, I guess that's from the setting MIN_KERNEL_SUPPORTED in debian/sysdeps/linux.mk. Given that stable has kernel 3.16 the probably easiest solution would be to bump the dependency to >= 3.16?!
