So it does look like some difference in the CRTs that is responsible

It need not exactly be a "difference in the CRTs". When perl uses one CRT and the compiler uses a different CRT, you can get situations where something (eg a handle) is created by one CRT and then passed to the other CRT (which knows nothing about that handle, and segfaults).

This problem arises when you try to build Win32::SharedFileOpen - which is the only example I know of, btw. A little surprising (at first glance) is the fact that you can build Win32::SharedFileOpen on ActivePerl using the MinGW compiler ... but it's not really surprising, because MinGW uses the same CRT as ActivePerl.

Fwiw, the original script you provided builds fine for me on ActivePerl using MinGW.

Cheers,
