Overview: If you are in a scenario where you have a failing call to check_circuit and wish to get more information out of it than just the gate index, you can use this feature to get a stack trace, see example below. Usage instructions: - On ubuntu (or our mainframe accounts) use `sudo apt-get install libdw-dev` to support trace printing - Use `cmake --preset clang16-dbg-fast-circuit-check-traces` and `cmake --build --preset clang16-dbg-fast-circuit-check-traces` to enable the backward-cpp dependency through the CHECK_CIRCUIT_STACKTRACES CMake variable. - Run any case where you have a failing check_circuit call, you will now have a stack trace illuminating where this constraint was added in code. Caveats: - This works best for code that is not overly generic, i.e. where just the sequence of function calls carries a lot of information. It is possible to tag extra data along with the stack trace, this can be done as a followup, please leave feedback if desired. - There are certain functions like `assert_equals` that can cause gates that occur _before_ them to fail. If this would be useful to automatically report, please leave feedback. Example: ``` [ RUN ] standard_circuit_constructor.test_check_circuit_broken Stack trace (most recent call last): #4 Source "_deps/gtest-src/googletest/src/gtest.cc", line 2845, in Run 2842: if (!Test::HasFatalFailure() && !Test::IsSkipped()) { 2843: // This doesn't throw as all user code that can throw are wrapped into 2844: // exception handling code. >2845: test->Run(); 2846: } 2847: 2848: if (test != nullptr) { #3 Source "_deps/gtest-src/googletest/src/gtest.cc", line 2696, in Run 2693: // GTEST_SKIP(). 2694: if (!HasFatalFailure() && !IsSkipped()) { 2695: impl->os_stack_trace_getter()->UponLeavingGTest(); >2696: internal::HandleExceptionsInMethodIfSupported(this, &Test::TestBody, 2697: "the test body"); 2698: } #2 | Source "_deps/gtest-src/googletest/src/gtest.cc", line 2657, in HandleSehExceptionsInMethodIfSupported<testing::Test, void> | 2655: #if GTEST_HAS_EXCEPTIONS | 2656: try { | >2657: return HandleSehExceptionsInMethodIfSupported(object, method, location); | 2658: } catch (const AssertionException&) { // NOLINT | 2659: // This failure was reported already.
