I just debugged the problem: apparently mmap() fails in cygwin in subtle
ways (i.e. it returns success, but not all the memory requested is
actually mmapped and when we access it we segfault). I disabled the mmap()
and now all the test pass but the ones that use P/Invoke and internalcalls
(I used the corlib built for linux, but there's probably something wrong
with the call convention default on win32 being different).
Hope this is useful (and that someone steps forward and sends a patch to
use the native interfaces for mmap in win32 :-).
