An issue was discovered in mruby 1.4.1. There is a NULL pointer dereference in mrb_class_real because class BasicObject is not properly supported in class.c.
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.
