[ruby-core:89819] [Ruby trunk Bug#14714] Ruby 2.5.1 Segmentation Fault in GC

From: aselder@...
Date: 2018-11-15 17:37:26 UTC
List: ruby-core #89819
Issue #14714 has been updated by aselder (Andrew Selder).


I'm also running into this same SegFault while running a Rails app (https://bugs.ruby-lang.org/issues/15308).

Same symptoms, Mac OS X, and segfault in rb_execution_context_mark()

Bug #14714: Ruby 2.5.1 Segmentation Fault in GC

----------------------------------------
I am using Ruby 2.5.1, and running ruby on rails 5.1.4 with rspec-rails 3.7.2 and capybara 3.0.2.

When I run my feature tests, i.e. rspec spec/features, I get a segmentation fault.  When I found the test in which  the fault is occurring, and run that test by itself, then the fault does not appear. If I make the offending test pending,and run rspec spec/features again, then the fault still occurs but in another test.  Accordingly, I cannot give you the exact code that is causing the fault.

I have attached the crash report log file.
