------- Additional Comments From dhazeghi@yahoo.com  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 :-)
