Areas of possible concern include calls to external procedures, alignment in ‘EQUIVALENCE’ and/or ‘COMMON’, generic interfaces, BOZ literal constant conversion, and I/O and calls to intrinsic procedures when passing a value to the ‘kind=’ dummy argument. Inspection of the intermediate representation of the translated Fortran code, produced by ‘-fdump-fortran-original’ or ‘-fdump-tree-original’, is suggested. Note, anything that is implemented in Fortran and included in libgfortran may suffer from a change in ABI.
