--- Comment #41 from Kostya Serebryany <kcc at gcc dot gnu.org> 2012-12-21 08:11:19 UTC --- Wild guess: does Fortran have any custom unwinding mechanism (like exceptions in C++ or longjmp in C)? For C/C++ we've spent quite some time to get rid of false stack-buffer-overflow reports caused by exceptions and longjmp.
