I read the thread, but don't see anything that warranted that particular change. You provided workable solutions to the problem that the original poster had and in the end the problem was solved: "I've solved the problem by creating a small module that allows to execute, from a coroutine, a function in the main thread. It helps to keep the main thread code independant from the coroutine code. My application works fine now, thanks for the help." > How exactly are you using the coroutines?

No, wxFrame can't live for longer than the life of coroutine. It is indeed for ZeroBraneStudio, but indirectly; the IDE itself doesn't depend on this, but the debugging component (provided by MobDebug: https://github.com/pkulchenko/MobDebug) does. The logic in question is part of the controller() function and is a completely generic code: local coro_debugee = coroutine.create(debugee) debug.sethook(coro_debugee, debug_hook, "lcr") local status, err = coroutine.resume(coro_debugee) It creates a coroutine for debugee (which is a function created as a result of loadstring/loadfile, for example, debugee = loadfile('minimal.wx.lua')), sets a debug hook on it and resumes it. All wxlua logic is encapsulated there, but with this fix the execution fails. > The issue is that doing this is dangerous and sometimes you have to > stop people from trying to shoot themselves in the foot. It may be a valid reason in some cases, but I think in this case it broke a completely legitimate use of this functionality. In fact, in the original case the user was getting a reasonably informative error. >> been working fine before in many different situations (I have never >> had a single problem with it) and this is a deal breaker for me.
