vm_insnhelper.c: dump iseq
* vm_insnhelper.c (vm_stack_consistency_error): raise a fatal error with the disassembled instruction sequence, in the development version, instead of very rarely useful rb_bug in such case. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59211 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
