[BUG] core dump when ~10% of swap used

[jmakov]

Describe the bug

When memory starts to get consumed and swap starts to build up, btop stops updating and after a few seconds dumps core

To Reproduce

High mem env + swap buildup

Expected behavior

Would expect to update normally and just run

[megascrapper]

Had a similar issue where on 100% swap usage and 95-100% RAM usage it freezes for a moment before aborting with the message terminate called without an active exception.

There are no OOM killers acting on the btop or terminal & shell processes.

• Binary: binary from Arch repo
