Bug ID: 108253 Summary: [13 Regression] ICE in set_nonzero_bits Product: gcc Version: 13.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization Assignee: unassigned at gcc dot gnu.org Reporter: law at gcc dot gnu.org Target Milestone: --- Target: x86_64 Created attachment 54167 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54167&action=edit Testcase I'm assuming this is a regression as I suspect the abseil-cpp package was around and built during the f36/f37 gcc-12 cycle. g++ -O2 ./absl/strings/CMakeFiles/absl_cord_ring_reader_test.dir/cord_ring_reader_test.cc.ii during GIMPLE pass: dom /builddir/build/BUILD/abseil-cpp-20220623.1/absl/strings/cord_ring_reader_test.cc: In member function 'virtual void absl::lts_20220623::cord_internal::{anonymous}::CordRingReaderTest_DefaultInstance_Test::TestBody()': /builddir/build/BUILD/abseil-cpp-20220623.1/absl/strings/cord_ring_reader_test.cc:58:1: internal compiler error: in set_nonzero_bits, at tree-ssanames.cc:464 58 | TEST(CordRingReaderTest, DefaultInstance) { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ libbacktrace could not find executable to open Please submit a full bug report, with preprocessed source. See <http://bugzilla.redhat.com/bugzilla> for instructions. I haven't reduced or debugged this at all. It could well land on me as it's failing in DOM. It could also well land on Aldy/Andrew since I suspect it's touching ranger from inside DOM.
