Issue #14334 has been updated by PragTob (Tobias Pfeiffer).


Hello! Here is the corresponding simplecov issue: https://github.com/colszowka/simplecov/issues/652 (maintainer here) - I'm stumped as to what happens. Would happy to find the source but also to find a work around that I could publish :D

Bug #14334: Segmentation fault after running rspec (ruby/2.5.0/erb.rb:885 / simplecov/source_file.rb:85)

----------------------------------------
Segmentation fault after running rspec (ruby/2.5.0/erb.rb:885 and simplecov-0.15.1/lib/simplecov/source_file.rb:85)

Intermittently receiving a segmentation fault as rspec test suite is finishing up run of about 400 tests on a Rails application.  No good way to effectively reproduce this as I can also get through complete rspec test runs without issues.

Attached console output and log file from DiagnosticReports folder.

Never experienced the issue when working with ruby 2.4.2p198 (2017-09-14 revision 59899) [x86_64-darwin16]

Please let me know what else you might need to diagnose.
