System: Linux fanzthesecond 2.4.18 #33 Thu Jul 18 04:56:44 CEST 2002 i686 unknown
Architecture: i686

	
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc-20020916/configure --program-suffix=-xp --prefix=/usr/local --enable-languages=c,objc
>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
