From ac41c2c1322b0ff4ed363e05fd03d9cfcc1ced55 Mon Sep 17 00:00:00 2001 From: normal Date: Sat, 7 Jul 2018 23:59:23 +0000 Subject: [PATCH] process.c (rb_f_exec): pause MJIT before replacing process Non-parallel "make test-spec" caused spec/ruby/core/process/wait2_spec.rb failures because mspec uses "exec" in single-process mode, so there's no chance the post-exec state could know about the MJIT child process from its pre-exec state.
