Bug #: 53943
Summary: Compiler ICE with -fobjc-direct-dispatch flag on Linux
Classification: Unclassified
Product: gcc
Version: 4.6.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: objc
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: kostja.osi...@gmail.com
GCC Objective C compiler fails with an ICE when flag -fobjc-direct-dispatch is
set on Linux. I am aware that this flag is for Darwin, however, ICE is never a
good idea. Better to ignore the flag with a warning.
kostja@atlas:~$ cat foo.m
#include <objc/runtime.h>
#include <objc/Object.h>
@interface Interface: Object
+ (id) new;
@end
@implementation Interface
+ (id) new
{
return class_createInstance(self, 0);
}
@end
int main()
{
@throw [Interface new];
}
kostja@atlas:~$ gcc -fobjc-direct-dispatch foo.m -lobjc
foo.m: In function ‘main’:
foo.m:14:2: internal compiler error: Segmentation fault
