[Mingw-users] Here's a nice gcc bug for you to play with :-)

[Mark J. <sn...@sn...>]

/*
Hi,
I've reported this GCC bug, but I thought I'd better post it here too
in case there are people around who could fix gcc or tell me my code
is wrong  :-)

Compile with g++ -c, should get an internal compiler error #373.

Cheers,
Mark Jordan.
