Bug #9856: [PATCH] process.c (proc_getgroups, proc_setgroups): use ALLOCV_N

• Status: Closed
• Assignee: normalperson (Eric Wong)
• Target version: 2.2.0
• ruby -v: ruby 2.2.0dev (2014-05-19 trunk 46010) [x86_64-linux]
• Backport: 2.0.0: DONE, 2.1: DONE

[normalperson (Eric Wong)]

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.
