I debugged a STATUS_ACCESS_VIOLATION problem that I encountered when
trying Mercury on cygwin32 version b19.1. As it happens, the problem
was due to the version of gcc distributed with b19.1 generating
incorrect code, rather than any of the alternatives 1-3 above.

A STATUS_ACCESS_VIOLATION is a quite common diagnostic which can have
a range of different causes, and in this particular case I don't think
the problem was related to the use of fork().
As I said in my previous mail, the problems have been solved in
the lastest snapshot of the Mercury distribution and in the versions
of egcs/binutils available at Mumit Khan's site.
