Issue #10034 has been reported by Eric Wong.

----------------------------------------
Feature #10034: [PATCH] (struct re_pattern_buffer): reduce by cache line
https://bugs.ruby-lang.org/issues/10034

* Author: Eric Wong
* Status: Open
* Priority: Low
* Assignee: Eric Wong
* Category: regexp
* Target version: current: 2.2.0
----------------------------------------
Reducing struct re_pattern_buffer from 464 to 448 bytes allows it to fit
into neatly into seven 64-byte cache lines on x86-64 systems.

ABI is changed in 2.2.0dev anyways, so we may do this.
Will commit in a few days.
C extension users will need to rebuild extensions for this.
There'll probably be more changes like this (rb_io_t, maybe others).
