Well, regression testing works if you can a) compile, b) know a previous version where everything worked, and c) know how to use git.
Basically what you do is find a commit where it worked and later a commit where it broke, and then you can just bisect between them until you find the exact commit which broke it.
Usually at that point finding the bug is a lot easier.

Here's the wine tutorial for regression testing, different program but same principle: http://wiki.winehq.org/RegressionTesting
Just ignore anything about compiling and replace with lmms compiling instructions.

Yes, it did create the bug. After reverting the commits, it does not
crash anymore. Will have a look at it. Maybe Devin (the author of
multi track export) has a solution already?
