Tested with GCC 4.4.1 and 4.4.3 (custom built) on Arch Linux
host arch is x86_64 and target is arm-elf

This is the full source code needed to reproduce the bug:

void __data_abort(void) __attribute__ ((naked));
void __data_abort(void)
{
  long foo;
  long* bar = &foo;
}

test.c: In function ‘__data_abort’:
test.c:5: warning: unused variable ‘bar’
test.c:5: internal compiler error: in expand_expr_addr_expr_1, at expr.c:6835
