Issue #8154 has been reported by marcandre (Marc-Andre Lafortune).

Bug #8154: Remove/fix rb_check_block_call
https://bugs.ruby-lang.org/issues/8154

Author: marcandre (Marc-Andre Lafortune)
Status: Open
Priority: Normal
Assignee: nobu (Nobuyoshi Nakada)
Category: core
Target version: current: 2.1.0
ruby -v: r39877


Looking back in the history, I found that commit r36989 (abeedb0875f3) introduced rb_check_block_call, but (1) it uses obsolete rb_iterate and (2) it created a strange bug [#8153].

In r39877, I used rb_respond_to + rb_block_call instead. This way Array#zip is similar to Enumerable#zip and Lazy#zip.

rb_check_block_call should either be removed or fixed to avoid r36989.
