You have to used global labels for subroutines, then all is fine.
But being able to craft input that causes IMCC to segfault (actually
any form of segfault) is bad on principle, isn't it?


For sure. But this is slightly a different problem. The error happens at 
runtime and can easily reproduced by this totally syntactically valid 
program:

        bsr -1
        end
The error is caught at runtime only with the -b or -t switch. The same 
holds of course for branching e.g. inside of an instruction or past the end.
