Diagnostics, 27. Input/Output, TR1.6 - Containers Versions: 4.1.3 Environment: SuSE SLES 9sp2 (ppc64), IBM XL C/C++ Advanced Edition V8.0 for Linux Version: 08.00.0000.0000 Reporter: Scott (Yu) Zhong I'm working on a problem with tests/stdlib/string/io.cpp, it is seg faulting at exception.cpp. I noticed when I used gdb64 to debug it, it would call "throw (__rw_failure&)" twice in the __rw_throw_exception function. Can this be the cause of seg fault? When it calls throw twice? Looking at other failed stdlib test causes me to think .__cxa_get_globals_fast () in libsup++ is the most likely cause of segmentation faults in those test.
