Hard to say exactly - it could well be an issue with how tgc is doing things. However you should first try making sure your tests are running one function call deeper than main:

This fix seems to work. Asan still returns a stack buffer overflow error, but my tests now consistently succeed.
Thank you for such a quick response.

The way tgc scans the stack is probably causing Asan to report it as an overflow. In general it does so safely but it definitely makes tools like memory sanitizers worried!
