------- Comment #5 from jakub at gcc dot gnu dot org 2010-02-19 13:45 ------- Heh, have just been looking into this too and figured out it is the alignment, already in *.expand dump. With -O2 as opposed to -O1 the testcase now succeeds for both -m32 and -m64 though (but I have in my tree PR42897, PR43051 and PR43077 fixes).
