------- Comment #4 from craig dot lawson at centrify dot com 2007-03-12 18:26 ------- Perhaps there are different degrees of thread safety here.
If I write my multi-threaded program such that only one thread does stream I/O with libstdc++, I would expect it to operate safely with respect to the locale issue. But it will not: any other thread which modifies errno (via set_errno) is potential trouble for my stream I/O thread. On the other hand, if __convert_to_v was compiled to use the errno address function, my program would be correct. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31117
