libopenmpt before 0.4.3 allows a crash due to a NULL pointer dereference when doing a portamento from an OPL instrument to an empty instrument note map slot.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
