    I believe this is addressed by what will shortly become game-music-emu 0.6.2, containing a fix for what seems to be the precise issue, along with a minimal bit of additional hardening. If that is uncool for Debian packaging then I made sure to split out the smallest possible fix as a separate commit so it can be applied on its own if need be.

    Note that I wasn't able to reproduce the precise issue on my system with the crasher file, but there was a useful backtrace in the linked information that seems to confirm the logic error upon inspection.

    The signed tarball for 0.6.2 is now available from the Downloads page. I believe this resolves the proximate issue (I suspect others will still lurk however!). But if you can still reproduce, please reopen.

    Thanks for the fast response!

    From what I can see, you only fixed this issue and added some more checks (thanks!) but there don't seem to be any other functional changes. That should be fine
