Well, actually, the plain non-compiled version did only work when the version of one of the dependencies was correctly set. I don’t know whether this is related, but after fixing this, the error upon running the compiled version changed, and seems to give a little bit more information about the cause of failure:
fatal: error thrown and no exception handler available.
MethodError(f=typeof(Base.convert)(), args=(Int32, nothing), world=0x00000000000066d2)

I do use convert explicitly in one function of the main library used by the program:
$ grep convert src/QafDemux.jl
qualnum2prob(qual::Int64) = qualnum2prob(convert(UInt8, qual))
I still don’t understrand how to fix the issue, though.
