That's the same observation Marco made in http://cygwin.com/ml/cygwin/2010-02/msg00257.html and it points to a problem in the new, multibyte-aware regex imported from FreeBSD. The change between 20100204 and 20100205 was a trivial change to silence a cheeky gcc, and it only sets locale variables, which were undefined before,,, to a start value of 0. Nothing else happened, but still, now we have a misbehaving regex. How disappointing. The simple fix would be to revert to our old regex implementation, but that would mean to give up multibyte-awareness again. A bit more complex but more satisfying in the long run is to find out what exactly is going wrong. What I need is a simple testcase, either a very small piece of plain C code which shows the problem with regcomp/regexec, Or, if you're not fluent enough in C, it would help to have the input string and the search string which misbehave, like this" Input string: "The quick brown fox jumps over the lazy dog." Search string: "f.x" In the meantime I'll have a look to see if I find anything obvious.
