This is a problem with the locale you are using - for whatever reason it doesn't contain a std::collate<char> facet - as it's required to do so by the standard.

You could try and reproduce with:

std::locale l;
std::use_facet<std::collate<char> >(l);

and see if that also throws.

If it does, I'm not sure what the cause/solution is - it certainly should be reported to the libstdc++ developers if it's reproducable. I'm also not sure why we don't see this problem on any of our MacOS test machines. As a workaround you could try defining BOOST_REGEX_USE_C_LOCALE in boost/regex/user.hpp so the library doesn't use the C++ locale at all (and rebuild obviously).

One final check, I note that you're building the library with _GLIBCXX_DEBUG defined, I assume that your app is also built with that defined? If not it will crash for sure as in general you can't mix object files with and without that define.

HTH, John.
