Research direction

Start with the linked GitHub Actions run and its Valgrind output for the nightly GCC, asserts=ON, shared=OFF configuration. Examine the listed FIRRTL and LLHD simulator tests to identify the common failure, then verify that the 13 failures pass without Valgrind errors in the same configuration.
