test program

This is a small test program from the ppl library tests.

clang test.c
a.out // hangs
a.out 1 // crashes

This is reproducible in gcc 4.7 (see below).

It also crashes when compiled with the PellesC compiler
(http://www.smorgasbordet.com/pellesc/).


I am running Windows 7 64-bit.


Here is the build of gcc I used to build Clang:

(mingw64 project also lets you cross-compile mingw32 and mingw64 builds on
Linux)

mingw64 toolchain sources with build scripts to create cross-compilers:

mingw64 toolchain binaries:

http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/rubenvb/4.7.0-1/


This wiki page has a good explanation of how to set up mingw64 and build OCaml
on Windows 64-bit:
