Issue #15406 has been reported by wanabe (_ wanabe).

----------------------------------------
Bug #15406: Loaded iseq may cause SEGV on GC
https://bugs.ruby-lang.org/issues/15406

* Author: wanabe (_ wanabe)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.6.0dev (2018-12-13 trunk 66370) [x86_64-linux]
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
Attached `test.rb` causes SEGV on trunk r66370.
`test.log` is stderr log.

I don't known what `[0, 13, 0]` means, but I guess environment dependent.
`./miniruby test.rb 4 17 0` also causes SEGV on mn environment but `./miniruby test.rb 4 16 0`  doesn't.

Note:
I've found the issue during the investigation of #15395, but I don't know it is related or not.
