Node.js Question

node js script crashes: Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

My script crashes and debugger is unable to catch the error. I even tried to try catch some functions but it didnt work.

Any suggestion how to narrow down where the problem could be?

The script is a testing script for a game. It works good for previous games, but for new game there are some new cases. Unfortunately I cannot know where is the error. Probably when unique case object is received from server.

The script is testing against the server and writing output to either console or file. In both cases error happens.

The exit code (139) means a segmentation fault occurred (128 + 11 (for segfault)).

You can use the segfault-handler module to debug the segmentation fault. You can use it like so:

var SegfaultHandler = require('segfault-handler');

SegfaultHandler.registerHandler("crash.log"); // With no argument, SegfaultHandler will generate a generic log file name

// Write the cause that causes the segmentation fault here

You should see a stack trace that you can now debug using tools like objdump -dS module.node.

objdump displays information about one or more object files.
