It looks like this is some kind of varargs misuse, since it seems to bomb out when formatting The opcode %s was given invalid operands and it looks like the parameter is null.
A file containing only the string
b((no newline) causes the assembler to crash. Stack trace looks like this:It looks like this is some kind of varargs misuse, since it seems to bomb out when formatting
