I like Haxe, mostly, it's a nice language, built by passionate people. Typescript has replaced it in our cooperate projects, but I still love building tools in Haxe. Just to keep it fun.
(Interestingly, in my experience the C++ target is rock solid. Though that experience is from many years ago.)
In any case, the best source for known compiler bugs is always gonna be GitHub:

Haxe makes it really easy to get started and get a feel for things, just have a go! I found the opposite with Typescript, where it seemed like I had to already be a javascript developer to use it.
