Cutter freezes when scrolling disassembly about cutter

[karliss]

If you scroll at moderate speed do you see a bunch of warnings in the builtin console widget?

also now i'm not so sure that wayland is related, i'm now getting freezes in X when trying to open the same executable again.

[karliss]

Ok this looks like combination of two problems:

• the old problem of deadlocking on too much console output #2070
• an issue with pcre2 in rizin -> it shouldn't spew that much errors under normal usage probably same issue as what rizinorg/rizin#4329 attempted to fix

[Rot127]

I cannot reproduce it on Debian. And the PCRE2 and NixOS issues don't mention problems with JIT anywhere.
This will need a little time until I have set up a NixOS VM. Also because we want to report this to the PCRE2 folks. But we could just disable JIT for NixOS as well.

[Rot127]

@praschke Setting up NixOS takes pretty long for me (installing qt6/5 doesn't work and more). And I don't know unfortunately, when I will find time to take care of it.

So if you are willing, you can test the following patches, which disables JIT for the regex engine.

If they do work, it means NixOS has problems with the PCRE2 JIT as well. We shoud report this in NixOS/nixpkgs#300056 in this case. And than see how they'd like to solve it.

Diffs

They are for rizin. Not for Cutter. So they need to be applied in the rizin submodule.
