Essentially a regression on the partial fix for https://bugs.webkit.org/show_bug.cgi?id=181723 (Unhandled Promise Rejection: Error: Out of executable memory in function at index)
To reproduce with any beta of iPad OS 13:
1) Navigate with Safari to https://simulations.kognito.com/changetalk/dev
2) Notice the compiler crash immediately when attempting to load
For clarity, iOS 12.2, 12.3, 12.4 all function correctly. Any version *before* 12.2 will result in the same error that currently happens in iPad OS 13. Let me know if there's any other information or test case you need from me.
Just wanted to add that I got around to installing iOS 13 beta (version 8) on my iPhone X and the regression exists there too. I'm sure not too surprising, but just thought I'd share for clarity's sake.
Thanks for letting us know. We’re actively working on making JSC use less executable memory for Wasm in ToT WebKit.
This issue should be fixed via bug 200807, sorry for the forward dupe.
