H A D | Makefile.inc | diff 248672 Sat Mar 23 23:42:11 MDT 2013 dim Compile contrib/tzcode/stdtime/localtime.c with -fwrapv, since it relies on signed integer overflow wrapping. Otherwise mktime(3) and timegm(3) can hang, in case the timestamp passed in struct tm is not representable in a time_t. Specifically, any timestamp after 2038-01-19 03:14:07, in combination with a 32-bit time_t. Note that it would be better to change the code to not rely on undefined behaviour, but it is contributed code, and it is not entirely trivial to fix the issue properly. MFC after: 3 days |
