[tbfleming]

Is this when you build using the provided CMakeLists.txt?

[tbfleming]

I think I see what's happening. The compiler version you're using doesn't notice that code can't execute. I have those lines for debugging odd cases; I set catch_all to false and set breakpoints on those lines. I might just strip that out.

[cc32d9]

it's gcc 8.2.0, using my own cmake files
