           Summary: Error message mentioning _OBJC_INSTANCE_0
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P3
         Component: objc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: nicola@gcc.gnu.org


The following testcase --

#include <objc/NXConstStr.h>

int main (void)
{
  if (@"Test")
    return 0;

  return 1;
}

when compiled with the GNU runtime,

gcc test.m -lobjc -fgnu-runtime -Wall

produces an error message which is correct, but confusing for users --

test.m: In function ‘main’:
test.m:5:7: warning: the address of ‘_OBJC_INSTANCE_0’ will always evaluate as
‘true’ [-Waddress]

The error message is confusing because _OBJC_INSTANCE_0 is the internal name
used for @"Test".

Thanks

Confirmed - I get this error message both on GNU/Linux 32bit and Apple 32bit.

Thanks
