Yep, I noticed that too - due to failures in i686-pc-linux-gnu
testresults coming in for 3.3.
If noone beats me to it, I'll look into it this weekend; however I do
not have a ix86 system anymore to test patches on - so I have to ask
someone else then ....

The regression show up with this patch:
Sat Jun 23 01:23:59 CEST 2001 Jan Hubicka <jh@suse.cz>
* flow.c (mark_set_1, attempt_auto_inc, mark_used_reg,
try_pre_increment_1): compute REG_FREQ using bb->frequency.
* regclass.c (loop_cost): Kill.
(frequency): New global variable.
(record_operand_costs): Replace loop_cost by frequency.
(scan_one_insn): Likewise.
(regclass): Likewise; set frequency according to bb->frequency.
* flow.c (split_edge): Set frequency.

State-Changed-Why:
Confirmed.
Here's a shorter testcase that crashes 3.2-branch, 3.3-branch and mainline
(as of 20030113) :(
----------------------snip here------------------
SUBROUTINE FOO (B)
10 CALL BAR(A)
ASSIGN 20 TO M
IF(100.LT.A) GOTO 10
GOTO 40
C
20 IF(B.LT.ABS(A)) GOTO 10
ASSIGN 30 TO M
GOTO 40
C
30 ASSIGN 10 TO M
40 GOTO M,(10,20,30)
END
----------------------snip here------------------
Just compile with "g77 -O2 -c" to get
bug.f: In subroutine `foo':
bug.f:13: internal compiler error: in compensate_edge, at reg-stack.c:2589
Please submit a full bug report, [etc.]
