After upgrading to OSX Sierra I am having an issue with random segmentation faults. It most commonly occurs when running rails test and I believe it is due to the sqlite3_adapter.
My present work around is to simply quit terminal and restart it. This works for about 1 or 2 rails test and by the third one I am almost guaranteed to get another segmentation fault.
Is anybody else having an issue with this or find a better workaround?

/Users/USER/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/activerecord-5.0.0.1/lib/active_record/connection_adapters/sqlite3_adapter.rb:27: [BUG] Segmentation fault at 0x00000000000110
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin16]
Edit:
After digging into the sqlite3_adapter.rb, I see that the line causing the segmentation fault is the creation of a new SQlite3 database.
db = SQLite3::Database.new(
config[:database].to_s,
:results_as_hash => true
)
Edit 2:
Rather than quitting and restarting terminal, I have found that running:
spring stop
stops the problem temporarily. Not a solution, but a better work around.
Edit 3:
This appears to be a problem with Apple's supplied libsqlite3 not being fork safe. More info can be found here:
https://github.com/sparklemotion/sqlite3-ruby/issues/195
For now, I have created an alias at the bottom of my ~/.bashrc file:
alias ss='spring stop'
When the problem occurs, I can now type:
ss
and then rerun the test.
Looks like a patch has been issued! The patch will look for sqlite3 in your brew folder instead of using Apple's supplied version by default. Simply run:
bundle update
to get the latest version of sqlite3-ruby and if you don't already have sqlite3 installed in your homebrew directory, run:
brew install sqlite3
