Bug ID: 112541 Summary: FAIL: 19_diagnostics/stacktrace/current.cc Product: gcc Version: 14.0 Status: UNCONFIRMED Keywords: testsuite-fail Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: redi at gcc dot gnu.org Target Milestone: --- Target: armv8l-unknown-linux-gnueabihf /home/tcwg-buildslave/workspace/tcwg_gnu_0/abe/snapshots/gcc.git~master/libstdc++-v3/testsuite/19_diagnostics/stacktrace/current.cc:52: test_max_depth()::<lambda()>::<lambda()>::<lambda()>::<lambda()>::<lambda()>::<lambda()>::<lambda()>::<lambda()>: Assertion '! t.empty()' failed. timeout: the monitored command dumped core FAIL: 19_diagnostics/stacktrace/current.cc -std=gnu++23 execution test Also: terminate called after throwing an instance of 'std::out_of_range' what(): basic_stack_trace::at: bad frame number timeout: the monitored command dumped core FAIL: 19_diagnostics/stacktrace/entry.cc -std=gnu++23 execution test It appears that __stacktrace_impl::_S_current returns an empty sequence of frames. It's possible that all the lambda frames are inlined, or skip+2 in stacktrace.cc causes us to skip real frames that we should keep, or maybe libbacktrace just doesn't work on this target.
