Hi,
I have obtained an ICE in expand_expr_real_1, at expr.c:6814 when trying to
build my code using OpenMP. I am using gcc version "4.2.0 20060422
(experimental)" on target x86_64-unknown-linux-gnu.
The problem appears also in the FC5 gcc4.1.0 version "gcc (GCC) 4.1.0 20060304
(Red Hat 4.1.0-3)".
Below you find to pieces of code which produce the problem, as well as the
output of gcc -v -save-temps.
The ICE disapears when removing all openmp directives and headerfiles. The ICE
disapears also when the function is a void instead of T1, and also if T1 is a
normal 'old' type.
If you need more info, just contact me.
With kind regards,
Klaas
