When running asgen on FreeBSD I get the following crash on extremely rare occasions:

Thread 1 received signal SIGBUS, Bus error.

I first thought this was an instance of the weird heisenbug, but that one appears when accessing a GResource - this issue is new! I will have a look, but most likely later (it's a low priority thing and will take a while to investigate), so if you find anything that would be of great help!
