------- Comment #33 from berndtrog at yahoo dot com  2005-12-05 18:53 -------
Compiling test.c with 4.1.0 20051202 or 4.2.0 20051202 works OK.

Compiling test.c with 4.0.3 20051123 still fails:

test.c: In function 'test':
test.c:46: error: unable to find a register to spill in class 'POINTER_REGS'
test.c:46: error: this is the insn:
(insn 18 116 20 0 (set (reg/v:SI 56 [ a ])
        (mem:SI (post_inc:HI (reg/f:HI 22 r22 [orig:59 D.1125 ] [59])) [2 S4
A8])) 14 {*movsi} (insn_list:REG_DEP_TRUE 116 (nil))
    (expr_list:REG_INC (reg/f:HI 22 r22 [orig:59 D.1125 ] [59])
        (nil)))
test.c:46: confused by earlier errors, bailing out
