FYI, this patch clearly doesn't fix all segfaults in 12658_thread-1, but
the crashes no longer appear in glibc locale related functions.
E.g. I get segfaults in
#0  0x0000002a957b3b40 in std::locale::name () from /usr/lib64/libstdc++.so.6
#1  0x0000002a957b5dd8 in std::locale::global () from /usr/lib64/libstdc++.so.6
#2  0x0000000000401cde in thread_main ()
#3  0x0000002a9565debc in start_thread () from /lib64/tls/libpthread.so.0
#4  0x0000002a95c30df3 in thread_start () from yy/libc.so.6
or
#0  0x0000002a95bd6c00 in strlen () from yy/libc.so.6
#1  0x0000002a957b3cc9 in std::locale::name () from /usr/lib64/libstdc++.so.6
#2  0x0000002a957b5dd8 in std::locale::global () from /usr/lib64/libstdc++.so.6
#3  0x0000000000401cde in thread_main ()
#4  0x0000002a9565debc in start_thread () from /lib64/tls/libpthread.so.0
#5  0x0000002a95c30df3 in thread_start () from yy/libc.so.6
, also malloc corruptions, etc.
