nickva commented on issue #551: [Jenkins] couchjs segfaults URL: https://github.com/apache/couchdb/issues/551#issuecomment-310684280 Found a deterministic instance of a segfault. Apparently this bit ``` ["reset",{"reduce_limit":true,"timeout":5000}] ["add_fun","function(doc) }{"] ``` Segfaults in `ubuntu12erlang183` docker image when running on Ubuntu 17.04 host. Haven't tried others. The same input is expected to generate an exception about an invalid function, and it does so for example in the `centos7erlang18` docker image running on the same host. It obviously doesn't always segfault because it runs as part of a test suite and it doesn't always crash in `ubuntu12erlang183`, sometimes it passes. It could be just my specific host / docker running combination triggered it. ``` (gdb) run Starting program: /usr/src/couchdb/apache-couchdb-2.1.0-2f539e0/bin/couchjs /usr/src/couchdb/apache-couchdb-2.1.0-2f539e0/share/server/main.js < bad.in warning: no loadable sections found in added symbol-file system-supplied DSO at 0x7ffff7ffa000 [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
