Svelte code with many function calls crashes on Webkit

[ambrt]

Describe the bug

If there are too many calls to a function, Epiphany (Gnu Web - Webkit) browser crashes.
Chrome and Firefox work ok.

I'm starting browser with cairo renderer.
WEBKIT_DISABLE_COMPOSITING_MODE=0 EPHY_LOG_MODULES=ephy-window.c EPHY_DEBUG_BREAK=stack WEBKIT_FORCE_SANDBOX=0 GSK_RENDERER=cairo flatpak run --verbose org.gnome.Epiphany

Is there anything on Svelte side that can be done with this?

This works on Safari on MacOS. It sounds like this might be an Epiphany specific bug?

[gterras]

Couldn't reproduce on Epiphany 46 / Debian or any other brother. Most likely setup related, try without rendering/logging options or without flatpack.

Thank you for checking. I assumed that WebKit is same in both. Might be something with this browser and my OS.

The stand alone version is 3.36.4 on Ubuntu 20 and it crashed. Same for Epiphany Canary via flatpak.

Flatpak without cairo renderer can't be run b/c of OpenGl and NVIDIA driver conflicts.

So it seems it has to be a problem with old OS and/or drivers.
