The problem is with pthread_getspecific call Suddenly it returns NULL although key is correct and pthread_setspecific on this key is called just once in the beginning So even if i patch the place where comp_err fails ( in ./mysys/my_lib.c function my_stat at "my_errno = errno" ) the mysqld itself fails in another place like this ( in my_delete )

Hello! Thank you for the bug report. I cannot repeat this segfault using the release version of OS X 10.7 (Lion): i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00) So I'm closing this bug as "Can't repeat". However, compilation will instead fail with: /mysys/my_init.c:103: warning: implicit declaration of function ‘pthread_init’ Technically, it can be debated if this is really a MySQL issue, however we have implemented a fix which avoids the problem. It is scheduled to be a part of MySQL 5.5.16. The changeset can be seen here: http://lists.mysql.com/commits/140413
