           Summary: [objc-improvements-branch] function pointers as ivars
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: objc
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: d dot ayers at inode dot at
                CC: gcc-bugs at gcc dot gnu dot org,zlaski at apple dot com
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

Declaring function pointers as instance variables causes an ICE (independent of
the runtime).

The example (I'll try to attach it as a file...):
#include <objc/Object.h>

@interface MyObject : Object
{
  BOOL (*ivar)(id, SEL, id);
}
@end
@implementation MyObject
@end

int main ()
{
  return(0);
}

compiled with:
gccObjCI -fnext-runtime -lobjc fncptrivar.m
will fail, (independent of -fgnu-runtime or -fnext-runtime).  The compiler reports:
fncptrivar.m:5: internal compiler error: tree check: expected identifier_node,
have indirect_ref in add_instance_variable, at objc/objc-act.c:6601
