            Bug ID: 2128
           Summary: pcreposix REG_STARTEND BSDism is not *BSD compatible

demonstrates bug -- see comments at top (head test.c)

If rm_so is greater than 0 it gives an answer that is
not compatible with the *BSD REG_STARTEND implementation.

Git's embedded copy of glibc suffers from the same problem
but it is outdated and current versions of glibc do give
a correct, *BSD compatible result for rm_so > 0 (and Git
happens to only ever use REG_STARTEND with an rm_so == 0).

The attached test.c file demonstrates the problem.
