Found during examination of objc.log of http://gcc.gnu.org/ml/gcc-testresults/2004-12/
msg00277.html

the exact version of GCC;

gcc version 4.0.0 20041205 (experimental)


the system type;

localhost:~ lars$ uname -a

7.2.1-1-root.obj/RELEASE_I386  x86 i386


the options given when GCC was configured/built;

localhost:~ lars$ /tmp/gcc/bin/gcc -v

[Bug objc/18862] [4.0 Regression] ICE on gcc-4.0-20041205/gcc/testsuite/objc.dg/selector-1.m

This is at least a 4.0 Regression, it worked with 3.3.2.
-Wselector -fgnu-runtime is enough to reproduce this bug and it is a bug and it happens on more than 
i686-darwin.

typedef struct objc_selector *SEL;
@implementation Foo
- (void) foo
{
  SEL a,b,c;
  a = @selector(b1ar);
}
@end

It is in fact a 4.0 regression only. It compiles with gcc 3.4 as of 
2004/10/15, but it fails with mainline from the same date.
