------- Comment #1 from burnus at gcc dot gnu dot org 2007-05-30 17:54 ------- -ftrapv only traps floating-point overflow - no integer overflows.
(This is not completely correct, as some systems seem to offer to send FPE also for integer overflows, see e.g. https://www.cisl.ucar.edu/docs/ibm/ref/fpe.html For x86 (32/64) platforms, this does not seem to be directly supported by hardware; in this case one would need to add manual checks, which are slow, cf. e.g. http://softwarecommunity.intel.com/isn/Community/en-US/forums/thread/30227217.aspx .) -> WONTFIX, unless you find a good method to trap integer overflows. -- burnus at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |WONTFIX http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32153
