BTW, it was compiled using clang and not gcc, if that matters.

Ok, I reproduced it. It happens when compiling with clang. Turns out the inline keyword is interpreted differently in gcc (specifically c89) and clang.
alonho commented
Fixed! thanks. And If you want to trace something, you need to call functions, not print statements (-:
alonho commented
You can pip install the new version (0.1.5)
gavrie commented
Works fine now. This is totally cool! It's going to be useful.
The question, of course: Will it succeed in tracing tlib? :-)

I'm optimistic
