[ruby-core:71558] [Ruby trunk - Bug #11404] Segfault when 'throw' occurs while loading a Ruby source file [PATCH]

Issue #11404 has been updated by Tomoyuki Chikanaga.

Backport changed from 2.0.0: REQUIRED, 2.1: REQUIRED, 2.2: REQUIRED to 2.0.0: REQUIRED, 2.1: REQUIRED, 2.2: DONE

r51292, r51439 and r51440 were backported into `ruby_2_2` branch at r52655.
r51292 seems required to r51440 works well.

Dear Ruby people,

Here is a fix for a segfault which can occur when requiring a Ruby source file inside a Timeout.timeout {} block. This may seem like a strange thing
to do, but it can easily happen unintentionally if you use libraries which 'autoload' their source files (like RSpec, Rails, etc).

I have observed this segfault in MRI 2.1.2 and 2.3.0.

Thanks,
Alex Dowad
