 Does not happen to me with gcc version 3.3 20021107 (experimental) on 
 i686-pc-linux-gnu
 or gcc version 3.3 20021029 (experimental) on powerpc-apple-darwin6.1 
 but did happen on gcc version 3.1.1 on i686-pc-linux-gnu.
 
 Thanks,

    With present 3.3 branch, I get

      x.m: In function `xyz':
      x.m:7: warning: `X' does not respond to `do_something'
    
    Does this indicate that the bug has been fixed?

>Description:
Declaring an object (rather than, what would be correct, a pointer to an
object) causes the compiler to crash when one tries to send a message
to that object. 

>How-To-Repeat:

Try to compile the following code:

@interface X {
}
@end

void xyz(X y)
{
	[y do_something];
}

A crash occurs:

crash_objc.m: In function `xyz':
crash_objc.m:7: internal compiler error: Segmentation fault
