Subject: [ruby-core:62694] [ruby-trunk - Bug #9856] [Open] [PATCH] process.c (proc_getgroups, proc_setgroups): use ALLOCV_N

Issue #9856 has been reported by Eric Wong.

----------------------------------------
Bug #9856: [PATCH] process.c (proc_getgroups, proc_setgroups): use ALLOCV_N
https://bugs.ruby-lang.org/issues/9856

* Author: Eric Wong
* Status: Open
* Priority: Normal
* Assignee: Eric Wong
* Category: core
* Target version: current: 2.2.0
* ruby -v: ruby 2.2.0dev (2014-05-19 trunk 46010) [x86_64-linux]
* Backport: 2.0.0: REQUIRED, 2.1: REQUIRED
----------------------------------------
On my Linux system, these may return up to 64K rb_gid_t entries for
a total of 256K stack usage, potentially triggering SystemStackError
or just a segfault.  Use ALLOCV_N for stack safety, especially since
these are not performance-critical methods.

Will commit in a day or two.
