Techniques on debugging runtime errors?

[Andrej Mitrovic]

I've found the problem and the solution, see this post:

I completely forgot that the VST standard has at least two different
implementations, v2.3 and v2.4. And I've also forgot that I need to
ask the DLL if it supports calling one of two different function
implementations. The problem was I was calling a function that's only
defined in the v2.4 standard, but this vendor-specific DLL conforms to
v2.3 and didn't have it.

So luckily this wasn't such a big problem at all. Yay! :)
