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.
