Segfault when running napajs on CentOS 7 #225

mnahkies · 2018-04-26T23:03:59Z

Impact:
Napajs is unusable on CentOS 7, and pressumbly some other RHEL distributions. I have tried both the pre-build binary automatically installed, and by forcing a rebuild using

npm install --save napajs --fetch=false --build=true

Reproduction:
On a Linux system with a working docker installation create the following two files side by side. Then execute reproduce.sh.

This will build a docker environment based on centos 7 that has the required tools (cmake, nodejs, g++, etc), clone the napajs repository, and build it.

The docker run command then attempts to run the napajs test suite against the newly build image. This fails with a segfault. This happens when I try to include napajs in my project as well.

The crash stacktrace looks like the known issue here - nodejs/node#17817

Please have a try if the crash happens on Node 8.10.0/8.9.4. If the answer is Yes on 8.10.0 and No on 8.9.4. That should be the same issue.

mnahkies · 2018-04-27T04:36:14Z

@fs-eire it worked (didn't crash) on 8.9.4, haven't had a chance to test 8.10.0 yet

I did some investigation. Thanks for the stack trace the root cause is identified:

Should have been fixed in 0.2.3

@mnahkies could you please have a try on the latest version?
