@Ladsgroup I'm not sure how that Travis setup is configured, but if you make it install HHVM 3.18.2+dfsg-1+wmf3, that should be fixed.TASK DETAILhttps://phabricator.wikimedia.org/T165074EMAIL

Just saying this also happens in travis instances causing Wikibase travis tests to fail. https://travis-ci.org/wikimedia/mediawiki-extensions-Wikibase/jobs/232431659 if there is anything specific needs to be done (like using 3.17 instead of 3.18) please tell me to apply

I've built new HHVM packages with a patch as proposed by upstream in https://github.com/facebook/hhvm/issues/7779, that avoids the segfault and makes the phpunit tests pass with 3.18 again. I'll upload the new packages later on, after that we can revert the HHVM

We should really use the new HHVM in testing first before going to production. If the tests are broken it means fix the tests/the underlying issue, not work around it by disabling the test and continuing to use the (now uncertain if that test actually found a bug) in

Ok, so a clean vagrant vm (with 4GB ram!), will segfault by running phpunit with no extensions

@MoritzMuehlenhoff we should probably downgrade the HHVM version from Beta and CI and work on repro'ing elsewhere. This is preventing merges and is UBN.TASK DETAILhttps://phabricator.wikimedia.org/T165074EMAIL
