Description Dominic Cleal 2016-04-28 14:44:58 UTC 
Description of problem:
Calling V8::Context.new causes a segfault in Ruby MRI. This is also seen when combined with rubygem-execjs and precompiling Rails application assets.

Version-Release number of selected component (if applicable):
rubygem-therubyracer-0.11.0-13.fc24

Installing:
 ruby                     x86_64     2.3.0-54.fc24             fedora      76 k

How reproducible:
Always

Steps to Reproduce:
1. ruby -rv8 -e 'puts V8::Context.new.eval("7 * 6")'

Actual results:
/usr/share/gems/gems/therubyracer-0.11.0/lib/v8/context.rb:66: [BUG] Segmentation fault at 0x00000000000018
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]

Expected results:
42

Additional info:
Works fine on F21-23, segfault is new in F24.

Can't test on Rawhide as v8 isn't built against the current icu package.

Fix SEGSEGV with GCC6

This seems to fix the segfault for me. The patch is based on

https://github.com/nodejs/node/issues/6272

Specifically this commit:

https://github.com/targos/node/commit/86c9184ef1083a56f3e05839783634b10707f9ca

But it needs some header cleanup ... I leave it to anybody else ;)
