ICE on mainline with m68k-uclinux (verify_stmts failed)

[Bernardo Innocenti]

Hello,

the following ice-on-valid-code appeared on mainline
between 2004-05-25 and 2004-05-29.
The source compiles fine with other versions of GCC, and
the error message is... err... funny.
I've committed two m68k patches by Peter Barada during this
time period, but I tried removing them and the ICE is still
there, so it must be something else.
Before filing a bug report, I'd like to know if anyone
noticed it already.  If not, I could try to hunt for
the exact patch that caused it.

The code near the error looks like this:

---cut---
   627 void _ppfs_setargs(register ppfs_t *ppfs)
   628 {
   629 #ifdef __va_arg_ptr
   630         register void **p = ppfs->argptr;
   631 #else
   632         register argvalue_t *p = ppfs->argvalue;
   633 #endif
   634         int i;
   635
   636 #ifdef NL_ARGMAX
   637         if (ppfs->maxposarg == 0) {     /* initing for or no pos args */
   638 #endif /* NL_ARGMAX */

Boring preprocessed code available on request.
