The ICE in PR analyzer/93382 is a validation error. The global variable "idx" acquires a "tainted" state from local array n1[0]. When the frame is popped, the svalue for n1[0] is purged, but the "taint" sm_state_map's entry for "idx" has a svalue_id referencing the now-purged svalue. This is caught by program_state::validate as an assertion failure. This patch fixes the issue by resetting the origin id within sm_state_map entries for the case where the origin id has been purged. gcc/analyzer/ChangeLog: PR analyzer/93382 * program-state.cc (sm_state_map::on_svalue_purge): If the entry survives, but the origin is being purged, then reset the origin to null. gcc/testsuite/ChangeLog: PR analyzer/93382 * gcc.dg/analyzer/pr93382.c: New test.

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.
