>Description:
If I have a function returning void but name its return value, and have it return it, ie:

void foo() return retval
{
     return retval
}

I get a internal compiler error:
foo.c: In function `void foo()':
foo.c:3: Internal compiler error in `expand_expr', at expr.c:5771
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.          

This is probably a trivial bug (I haven't looked at the source), but the compiler asked me to report the bug, so here you are.
>How-To-Repeat:
Type the trivial example function shown in the bug description to a file, and try to compile it with g++
>Fix:
Naming a void function's return value is obviously a stupid mistake from the coder's part, so to avoid the problem, don't do stupid mistakes :)
