[ruby-core:80559] [Ruby trunk Bug#13400] mcontext struct has differently-named members in OS X 10.4

From: mistydemeo@...
Date: 2017-04-04 11:52:08 UTC
List: ruby-core #80559
Issue #13400 has been reported by mistydemeo (Misty De Meo).

----------------------------------------
Bug #13400: mcontext struct has differently-named members in OS X 10.4
https://bugs.ruby-lang.org/issues/13400

* Author: mistydemeo (Misty De Meo)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.2.3p173 (2015-08-18 revision 51636) [i386-darwin8.0]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
The `mcontext` struct, used by Ruby in `signal.c` and `vm_dump.c`, has a different structure in OS X 10.4 than it does in later versions.

In OS X 10.5 and later, its members' names all start with a double underscore (`__`); in 10.4, they don't. Similarly, the `__ss`/`ss` struct's members all begin with `__`, for example `__esp`, while in 10.4 they don't, for example `esp`.

In addition, `vm_dump.c` is missing an `#include <ucontext.h>` in order to access the `mcontext` struct definition.

Usage in `signal.c` is here: https://github.com/ruby/ruby/blob/trunk/signal.c#L790-L794
Usage in `vm_dump.c` is here: https://github.com/ruby/ruby/blob/trunk/vm_dump.c#L460-L480 https://github.com/ruby/ruby/blob/trunk/vm_dump.c#L825

I tested using Ruby 2.2.3p173 and Ruby 2.4; the sections of these files in trunk are unchanged and still have the bug in question. I'm building for i386.
