Can you try to see if there are any warnings with -Wstrict-overflow ? If so it might be best if the source gets fixed. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |WAITING http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34841
