Description Rodrigo Kumpera 2018-04-20 10:38:42 PDT

Mobile safari crashes when accessing: https://learningblazor.azurewebsites.net

It started crashing with a recent update of the mono runtime.

It works on other browsers.

I should mention it works fine with the previous mono runtime, which has a larger WASM payload.

With Safari Tech Preview Release 54 (Safari 11.2, WebKit 13606.1.13.2)

This page crashes the browser in all sorts of places (crash logs not particularly useful): https://learningblazor.azurewebsites.net

It works with Safari 11.0.3 (13604.5.6).

From talking to Rodrigo, this is likely due to too much code getting generated, JSC runs out of X memory.

Comment 4 Rodrigo Kumpera 2018-04-23 06:59:15 PDT

I'm not sure whether it's related or not.

Here some of the device crash logs.

If there's anything else I can do to help, please don't hesitate do ask.
