[burnus at gcc dot gnu dot org]

The following examples run fine with -O1, but with -O2 they gfortran library
gives an error at run time.

$ gfortran -O gfortran.dg/interface_12.f90
$ ./a.out
$ gfortran -O2 gfortran.dg/interface_12.f90
$ ./a.out
Fortran runtime error: Attempt to allocate a negative amount of memory.

Analogously for gfortran.dg/result_in_spec_1.f90
