Problem with Ruby 2.7.6 and version 0.2.20

[samuelvaneck]

I've got issue's running the latest version of Stackprof, 0.2.20 on Ruby 2.7.6. The server crashes after 1-2 page clicks.

If needed I can provide the Diagnostic Reports.

FWIW the CI also seems to segfault or fail frequently: https://github.com/tmm1/stackprof/actions

I think https://github.com/tmm1/stackprof/pull/180/files#r951294711 is the bug

History of the related PRs, since I've been through them a couple times:

#172
#180

I think we can close this, #186 should fix it.

The MR should indeed fix the issue. We removed the gem from our repository since we didn't use it. I'll close the issue.
