This change is a followup to the fix for PR48776 (namely r14-3572-gd58150452976c4ca65ddc811fac78ef956fa96b0 AKA fortran: Restore interface to its previous state on error [PR48776]), which cleaned up new changes from interfaces upon error. Unfortunately, there is one case in that fix that is mishandled, visible on unexpected_interface.f90 with valgrind or an asan-instrumented gfortran. when an interface statement is found while parsing an interface body (which is invalid), the current interface is replaced by the one from the new statement, and as parsing continues, new procedures are added to the new interface, which has been rejected and freed, instead of the original one. This change restores the current interface pointer to its previous value on each rejected statement. PR fortran/48776 PR fortran/111291 gcc/fortran/ChangeLog: * parse.cc: Restore current interface to its previous value on error. |

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.
