[Bug c/18096] New: internal compiler error: in final_scan_insn, at final.c:2429

[lu_zero at gentoo dot org]

the trigger of the issue is part of openmotif (luckly is a optional little
component, and that's why nobody found it out before, openmotif itself builds
fine and the componente failure won't even break the buildchain), 

preprocessed source and source follows

built it with 
gcc -O2 -pipe -mcpu=7450 -mtune=7450 -maltivec -mabi=altivec
-fno-strict-aliasing -fsigned-char    -I../.. -I../../exports/include

(insn:TI 2000 4 1999 (set (reg:SI 0 0)
        (const_int -2147487920 [0xffffffff7fffef50])) 303 {*movsi_internal1} (nil)
    (nil))

Here is the reduced source:
void f(char*);voidmkcatdefs(char *fname) 
{
  char line [2147483647];
  f(line);
}

This causes a stack overflow anyways :).

Someone should fix the source not to do this.
