The ICE is caused by the presence of this insn:

(insn 124 118 128 2 (set (mem/s:SI (plus:SI (reg/f:SI 30 %r30)
                (const_int -100 [0xffffff9c])) [4 c.c+44 S4 A32])
        (const_int 0 [0x0])) 37 {*pa.md:2537} (nil)
    (nil))

The insn is emitted during expand as:

;; c.c[11] = 0
(insn 124 122 0 (set (mem/s:SI (plus:SI (reg/f:SI 90 virtual-stack-vars)
                (const_int 84 [0x54])) [4 c.c+44 S4 A32])
        (const_int 0 [0x0])) -1 (nil)
    (nil))

The fact that we have a conflict with a memory location used for
a general register save suggests that there is a problem with the
size of the frame for this function.
