I encountered the following message, where the actual data type is T_NONE (0x00).

./miniruby: [BUG] objspace/memsize_of(): unknown data type 0xb50ef290(0x00000000ffffffff)

There seems to be an improper handling of varargs in the function rb_bug_without_die.

A patch is attached to fix the issue. When it is applied the message becomes as follows:

./miniruby: [BUG] objspace/memsize_of(): unknown data type 0x0(0x0000000002948710)
