Hi Taco,

just out of curiosity: How do you actually debug such issues?
Are there extra tracing hooks in LuaTeX you can activate?
Do you compile a special version with extra debug prints?
Do you single-step through the TeX engine in a debugger?

Is there anything, we could use as well to diagnose problems?
