--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Mark Eggleston <markeggles...@gcc.gnu.org>: https://gcc.gnu.org/g:84b14e9cd4e05c926a75e8e97ee57dbd3350e752 commit r10-8697-g84b14e9cd4e05c926a75e8e97ee57dbd3350e752 Author: Mark Eggleston <markeggles...@gcc.gnu.org> Date: Mon Jun 1 08:15:31 2020 +0100 Fortran : ICE on invalid code PR95398 The CLASS_DATA macro is used to shorten the code accessing the derived components of an expressions type specification. If the type is not BT_CLASS the derived pointer is NULL resulting in an ICE. To avoid dereferencing a NULL pointer the type should be BT_CLASS. 2020-09-01 Steven G. Kargl <ka...@gcc.gnu.org> gcc/fortran PR fortran/95398 * resolve.c (resolve_select_type): Add check for BT_CLASS type before using the CLASS_DATA macro which will have a NULL pointer to derive components if it isn't BT_CLASS. 2020-09-01 Mark Eggleston <markeggles...@gcc.gnu.org> gcc/testsuite PR fortran/95398 * gfortran.dg/pr95398.f90: New test.
