Description Francis Herne 2017-03-23 13:15:03 UTC

I opened the file wp-includes/js/wp-api.js (part of Wordpress source) in KDevelop, over sftp in case it's relevant.

KDevelop hung, with the UI not being drawn. KDevelop was running in gdb, so I paused it at a random point after ~15s and got the backtrace below.

A few seconds after continuing, KDevelop got OOM-killed, apparently after requesting 21TB of memory. My laptop isn't that advanced yet.

Killed process 20762 (kdevelop) total-vm:21476475260kB, anon-rss:4774556kB, file-rss:0kB, shmem-rss:5532kB

ASAN warnings at the top might be relevant?

Comment 3 Francis Herne 2017-03-23 13:32:39 UTC

No debug symbols in Arch.
