--- Comment #24 from Sam Mish <samuelpmish at gmail dot com> --- > Good! Can you please provide steps how to build the reproducer project? Unfortunately, this project uses a large and unconventional build system, so it's difficult to reproduce. I could upload the `.ii` files, but each of the libraries in that /home/sam/code/serac_libs_gcc12/gcc-12.1.0/ directory were built custom (and might be relevant to the failure) I can look into trying to reproduce the issue in a docker image-- would that be helpful?
