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 <kargl@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 <markeggleston@gcc.gnu.org> gcc/testsuite PR fortran/95398 * gfortran.dg/pr95398.f90: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
