debuggers says: > signal SIGSEGV: invalid permissions for mapped object I get no results from rr (too slow).

I do not think I am capable to investigate this crash. I would be glad if somebody else takes this over. Starting point is https://github.com/servo/servo/pull/31194 (crashes can also be reproduced...

@CYBAI I did some cleanup on https://github.com/servo/servo/pull/31194, so you can base on it for your work and then rebase it on top of main. I usually built with `--production --with-asan`...

When `--with-asan` is used servo_allocator should use system allocator, not jemalloc. You can try building without asan, in that case you can attach debugger to running instance of servo. Here...

I never hit https://github.com/servo/servo/issues/29829 when running wpt tests via `mach test-wpt`, except when doing a lot of refreshing of WPT page.

I think the proper patch would be to use https://docs.rs/libc/latest/x86_64-apple-darwin/libc/fn.malloc_size.html. EDIT: Here is a PR with patch for it: https://github.com/servo/servo/pull/31602

I think you need `libegl1-mesa-dev`.

You posted that `libegl1-mesa-dev` is not installed, so you need to install it: ``` mirto@bianco500:~/Scaricati/servo$ sudo nala show libegl1-mesa-dev Package: libegl1-mesa-dev Version: 23.3.5-1 Architecture: amd64 Installed: no ```
