Test case, exhibits when linked to pcreposix

Running regcomp() from pcreposix library on 64-bit architecture where size_t differs to int can write broken value into re_nsub member of first argument.

This has been reported to upstream <http://bugs.exim.org/show_bug.cgi?id=1287> and fixed with commit:

r1024 | ph10 | 2012-08-29 13:08:24 +0200 (St, 29 srp 2012) | 2 lines
Fix re_nsub bug in the POSIX wrapper.

All Fedoras are affected.

Comment 4 Petr Pisar 2012-09-03 16:10:47 UTC 
pcre-8.21 is not affected, pcre-8.31 is affected. That means only Fedoras ≥ 18 are broken. The problem exhibits on PPC64. I cannot reproduce it on amd64.
