--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by David Malcolm <dmalc...@gcc.gnu.org>: https://gcc.gnu.org/g:5e10b9a28be9061b9b0c4aa3cfabe6d478e444e0 commit r10-6410-g5e10b9a28be9061b9b0c4aa3cfabe6d478e444e0 Author: David Malcolm <dmalc...@redhat.com> Date: Mon Feb 3 08:30:54 2020 -0500 analyzer: fix ICE merging models containing label pointers (PR 93546) PR analyzer/93546 reports an ICE within region_model::add_region_for_type when merging two region_models each containing a label pointer. The two labels are stored as pointers to symbolic_regions, but these regions were created with NULL type, leading to an assertion failure when a merged copy is created. The labels themselves have void (but not NULL) type. This patch updates make_region_for_type to use the type of the decl when creating such regions, rather than implicitly setting the region's type to NULL, fixing the ICE. gcc/analyzer/ChangeLog: PR analyzer/93546 * region-model.cc (region_model::on_call_pre): Update for new param of symbolic_region ctor. (region_model::deref_rvalue): Likewise. (region_model::add_new_malloc_region): Likewise. (make_region_for_type): Likewise, preserving type. * region-model.h (symbolic_region::symbolic_region): Add "type" param and pass it to base class ctor. gcc/testsuite/ChangeLog: PR analyzer/93546 * gcc.dg/analyzer/pr93546.c: New test.
