David, I've not seen or heard of anything like that before, the first thing
to check is that the regex tests work OK,

cd into libs/regex/test


bjam regex_regress

Assuming gcc-4 is your default compiler then that will build the main
regression test program *with static linking*.

If that works OK, then I bet there's some lind of binary incompatibity
between the lib variant that you're using and your program: try adding the
regex source direct to your program's build process and see if that works,
if it does I would suggest building the regex source into a static lib
yourself using whatever compiler options you're using.

However... I note that your program is calling exit explicity, there's just
an outside chance that there's some kind of bug either in the regex lib
initialisation/cleanup routines or in gcc-4.x. Or... maybe your program is
accessing the regex lib during it's cleanup routines, and finding that regex
has already destroyed it's globals? Those are just wildcard suggestions

HTH, John.
