That was enough to get to the crash while dumping, but since tzname is 
in the system headers, I think it is possible to find a better solution 
if we can make it work.

The crash is happening within the initialization code before any Emacs 
code gets run (__tmainCRTStartup). This code is calling _free_internal, 
which we are redefining in gmalloc.c. I'm not sure if this can be fixed 
without some major changes, so I'm inclined to put it aside until after 
the release.
