David, what happens if you say 

    wtext.reserve(1);

inside runTests() before the call to crash()?

If that makes the symptom disappear, I wonder if there’s some problem with a Cygwin *.exe owning a std::string that gets resized by a Cygwin *.dll.  If so, that probably *is* a memory ownership coordination problem that affects Cygwin proper.

I’ve run both versions under valgrind on a Linux box here, and they can find no fault with your code.  On manual inspection, I, too find it to be perfectly cromulent.
