not much help I am afraid, but I have had a few similar problems 
with native m68k-linux on 3.1. I managed to reduce one testcase 
to something really small, perhaps you can see something from it.

Btw it does no longer cause an ICE for 3.1.1 but the program from
which it is taken still doesn't work correctly.

#### compile with -O0 to trigger ICE ####

extern void (**table)(void);

typedef unsigned short uw16;
typedef unsigned int gshort;

register uw16 *pc asm("%a4");
register gshort code asm("%d6");


void QMExecuteLoop(uw16 *oldPC)
{
            table[code=(*(uw16*)(pc++))]();
}
