--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-01-16 07:17:58 UTC --- Created attachment 26336 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26336 patch I believe the problem is that INSN_ADDRESSES of the CALL_INSN is different from INSN_ADDRESSES of the NOTE_INSN_CALL_ARG_LOCATION that follows it (which is equal to the next insn). Will look at this in more detail shortly.
