------- Additional Comments From [EMAIL PROTECTED] 2003-06-02 10:19 -------
Confirmed with gcc 3.3 branch (20030531). Note that this problem does not occur
on arm-elf... I
have somewhat reduced the testcase, and included it. I've verified that the
backtrace of the crash
of the new testcase is the same to that of the old one (well, almost completely
the same). Looks
like move2add_note_store is getting passed NULL data from note_stores, and that
in turn is
getting NULL data from reload_cse_move2add. Hope this information is helpful to
someone :-)
