Safari WebAssembly: Maximum call stack size exceeded

[palkan]

What's interesting is that simply calling a recursive method hits the stack level too deep error at much higher values, see, for example: https://runruby.dev/?gist=84cc1d932b19755f45d9ec52b20567f2

Found another similar issue (and they suggest that the problem is Asyncify) : nbarkhina/DosWasmX#21 (comment)

A more recent issue: https://bugs.webkit.org/show_bug.cgi?id=284752

Just upgraded to 18.4 on MacOS and iOS and that fixed the problem (at least, for one of my apps).

I got some reports that this issue is reproducible on https://ruby-quiz-2025.storesinc.tech at Kaigi... 😢
I had a second look at this but it seems like our iseq_compile_each0 and pm_compile_node are consuming too wasm stack on WebKit.

Probably, older Safari? 18.4 came out just on March, 31st. I've checked the stores quiz on both MacOS and iOS—works fine.
