The automatic storage passed by reference bug has been fixed. However, the race condition still happens: crazylock-nlibc: crazylock.c:26: cache_get: Assertion `rwlock.__data.__nr_reader s <= n' failed. crazylock-nlibc: crazylock.c:32: cache_get: Assertion `rwlock.__data.__nr_reader s < n' failed. crazylock-nlibc: crazylock.c:32: cache_get: Assertion `rwlock.__data.__nr_reader s < n' failed. The boxes this bug happens on happen to have 2x dual-core Opteron 270. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
