Debug builds fail on Windows/MinGW

[JesseTG]

When building this repo on Windows using the provided Makefile, it fails with a series of errors that look like the following:

(There are a lot of templates here.)

The full error log is available here.

This occurred on Windows 10, with MinGW. The build command is make DEBUG=1 -j. Linux builds (with or without debug symbols) work fine, as do non-debugging builds on Windows.

Ah! It seems that replacing this use of -O0 with -Og solves the problem.
