Thanks for the hints!

I've checked with Microsofts TR1 implementation, and I get the same wrong
result, so the problem is not Boost, but the 3rd party application.

_HAS_ITERATOR_DEBUGGING=0 and _SECURE_SCL=0, but that wasn't enough.

If anyone had an idea which #defines and #includes are _not_ allowed for
boost::regex (or std::tr1::regex), that would be great!

But you're right: as it's not a Boost-specific problem, I'll try to get help
from the application's vendor.
