Heyo, the way the debugger works is by changing the compiler to generate code that communicates with the debugger at every step.
That means that if you want a module to be debuggable, it has to be compiled by the debugger's compiler, too. There's apparently currently no way to just force a full recompile of all used modules (transitively) in memory, but you can copy-paste the modules you're interested in into a "lib/" folder and just -Ilib on the commandline. just make sure to rm -rf lib/.precomp between runs, i think! hope that helps! - Timo
