>Description:
When I try compiling this program:

int ll(int k)
{
  return k<0?1234:0;
}

I compile with the command:
./xgcc -O1 -DCROSS_COMPILE -S -o - /local/fblasco/kk/kk3.c -save-temps

Compiler crashes with this report:/local/fblasco/kk/kk3.c: In function `ll':
/local/fblasco/kk/kk3.c:4: Internal compiler error in simplify_gen_subreg, at simplify-rtx.c:2439
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.


If I compile with -O0 (without optimizations), the compiler works OK.

>How-To-Repeat:
Try to compile the 3 lines of code I sent.
