I manually ran that failing compile step. The assembly looks like:

        move.l 8(%a5),%d1
        move.l 12(%a5),%d5
        .set .LI70,.+2
        move.w .L70-.LI70.b(%pc,%d1.l*2),%d0
.L147:
        moveq #6,%d2
        cmp.l %d1,%d2
        jbcs .L147
.L148:
        jmp %pc@(2,%d0:w)
        .align  2
.L70:
        .word .L63-.L70
        .word .L64-.L70
        .word .L65-.L70
        .word .L66-.L70
        .word .L67-.L70
        .word .L68-.L70
        .word .L69-.L70

and it's tripping up on the move.w. AFAICT, this is part of the
expansion of a switch statement inside the php_conv_qprint_decode_convert
function. BTW: that move.w is repeated 3 times in that function, leading
to the three errors.

Looks like a gcc bug. It *does* compile at -O however (but not -O2).

BTW: This is on:
NetBSD mac68k, CVS from 20080910T0002 UTC.
