--- Comment #17 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-12-02 21:25:32 UTC --- Revised patch posted at http://gcc.gnu.org/ml/gcc-patches/2012-12/msg00084.html. Also tested with a build of xplor-nih (a complex mix of c, c++ and fortran code) which has always had optimization issues with FSF gcc (as xplor-nih has its own heap memory manager routines in fortran). A build of xplor-nih with -fsanitize=address produced 41 failures out of 154 tests but all of the failures emitted AddressSanitizer output (often unknown-crash on address) rather than segfaulting.
