           Summary: Segmentation fault with -mint8
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gjl@gcc.gnu.org
            Target: avr


Turning on -mint8 for avr-gcc runs into segmentation fault. I see it in
4.6.1-RC1 and 4.5.2.

==========================

Source (empty file will do also):

char x;

==========================

Command line:

avr-gcc -S -v -mint8 foo.c

==========================

Output:
