Issue #11001 has been updated by Takehiro Kubo.
Same issue with recent ruby versions on Ubuntu 12.04.
I tried it with recent OS versions and found that
* Ubuntu 12.04 - Segmentation fault
* Ubuntu 12.10 - Segmentation fault
* Ubuntu 13.04 - No problem
* Ubuntu 14.04 - No problem
* Ubuntu 15.04 - No problem
* Debian 8.1 - No problem
IMO, this may be an issue of OS, not of ruby.

Fwiw, valgrind chokes here, too.
I tested valgrind 3.9.0 on CentOS 7.0 and also backported to
Debian 7.0 (wheezy).
I comment reserve_stack out when I'm debugging other problems
with valgrind.

SEGV depends on stack limit size with 'ulimit -s <size>' .
This shell script [ulimit_change_test.sh] can reproduce SEGV on my Debian environment.
my Linux environment is Debian/GNU Linux 7.8.
But, I cannot reproduce this SEGV on Amazon Linux environment.

This SEGV occurs in `reserve_stack()` function.
I suspect that the `buf[0x100]` size is too small for margin.
I attached patch to fix it.

On Ubuntu 12.04, stack size in emacs shell buffer is 8515 and
ruby gets segmentation fault. So I put 'ulimit -Ss 8192' in .bashrc
for workaround. (stack size in gnome-terminal is 8192.)
