wohali commented on issue #551: [Jenkins] couchjs segfaults URL: https://github.com/apache/couchdb/issues/551#issuecomment-311714266 So we've been talking this over on #couchdb-dev IRC. The working theory is: ``` <vatamane> jit + fortify source + extra stack protection causes segfault ``` On Ubuntu 12.04, our Docker images currently use Debian's package, which is what @nickva analysed above. I will change our 12.04 image to build SM from source using flags as recommended via https://paste.apache.org/2UId . I'm not going to put a lot of effort in here - Ubuntu 12.04 is officially EOL at this point. Also worth noting is that the equivalent Debian package has a `--disable-methodjit` (and wrapped in a `ifdef` for `platform==Debian` only), which should also bypass the bug as found. Our CentOS 6/7 images currently build SM from source but do *not* include the build options above. That is, The *package* builds (in couchdb-pkg) **do** use these options, though (derived from the official CentOS 7 js-devel package definition). None of this helps Ubuntu 14, though, which has shown multiple segfaults (including at least 2 recorded in JIRA), and should have the flags listed above as ideal. All of this mess, plus the problems with building SM1.8.5 with gcc6+, make me want to get a `couchjs-chakracore` out the door as soon as possible, maybe for 2.2. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
