 Replying to [comment:10 SergeyBiryukov]:
 > On PHP 5.2.17 (PCRE 8.02 2010-03-19), I get a crash with any backtrack
 limit value larger than 709.
 >
 > On PHP 5.4.29 (PCRE 8.32 2012-11-30), I don't get a crash even with a
 much larger value, 1,000,000,000.

 My hunch is this is the underlying issue. PHP 5.3.7 fixes a few regex
 related things, and -- best I'm aware -- #8553 et al would not occur when
 running WP on top of that PHP version or later.
