PR analyzer/96611 reports an ICE within the handling for unknown functions, when passing a pointer to something accessed via a global pointer, after an unknown function has already been called. The first unknown function leads to the store being flagged, so the access to the global pointer leads to (*unknown_svalue) for the base region of the argument to the 2nd function, and thus *unknown_svalue being reachable by the 2nd unknown function, triggering an assertion failure. Handle this case by rejecting attempts to get a cluster for the unknown pointer, fixing the ICE. gcc/analyzer/ChangeLog: PR analyzer/96611 * store.cc (store::mark_as_escaped): Reject attempts to get a cluster for an unknown pointer. gcc/testsuite/ChangeLog: PR analyzer/96611 * gcc.dg/analyzer/pr96611.c: 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.
