It seems that the name of an opcode is somehow a NULL pointer. It may be
interesting to see where in the opcode list does this happen. What is
printed, when using '-v -m1048583' flags, before the crash ?

I got this exact error a couple of days ago, and after some debugging
it turned out csound tried to load a buggy, stray .os file that for some
reason was hanging around. I think it was libosc-sock.os or something
close to that.
