Stefan Teleman created STDCXX-1066: -------------------------------------- Summary: SPARCV8 requires pthread_mutex_t and pthread_cond_t to be aligned on an 8-byte boundary Key: STDCXX-1066 URL: https://issues.apache.org/jira/browse/STDCXX-1066 Project: C++ Standard Library Issue Type: Bug Components: Thread Safety Affects Versions: 4.2.1, 4.2.2, 4.2.x, 4.3.x Environment: Solaris 10 Update 6 or later on SPARCV8 [32-bit] Defect is compiler-independent - in reality it only affects Sun Studio and GCC. Reporter: Stefan Teleman Fix For: 4.2.2, 4.2.x, 4.3.x
Starting with Solaris 10 Update 6, on SPARCV8, pthread_mutex_t and pthread_cond_t MUST be aligned on an 8-byte boundary. Misaligned access will result in either SEGV or SIGBUS. There are numerous places in the multi-threaded version of stdcxx where pthread_mutex_t and/or pthread_cond_t types are contained within an union, but with an enforced alignment different than 8. All these instances must be corrected, and #ifdef-guarded for SPARCV8. Patches to follow shortly, this is just opening the issue. Warning: the patchset resolving this issue is very large, and it affects a large number of files. -- This message is automatically generated by JIRA.
