           Summary: avr-gcc: Segfaults when compiled with the -mint8
                    option
           Product: gcc
           Version: 4.5.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: tnorth@fedoraproject.org


The compiler segfaults when code is compiled with -mint8 option.

This bug was previously reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=626889

Arch: reported to happend on i686 and x86_64.
GCC build: see below.

How to reproduce: compile and run the following code, as shown below.

/** \file testmint8.c */
#include <avr/io.h>

int main(void) {
  DDRB=0xFF;
  while(1)
    {
    PORTB++;
    }
}

Output:
avr-gcc -v -Wall -g2 -gstabs -O0 -fpack-struct -fshort-enums -std=gnu99
-funsigned-char -funsigned-bitfields -mint8 -mmcu=at90pwm3b -DF_CPU=8000000UL
-MMD -MP -MF"testmint8.d" -MT"testmint8.d" -c -o"testmint8.o" "testmint8.c"
-save-temps
Using built-in specs.
