I tried adding all possible entitlements from here: https://developer.apple.com/documentation/bundleresources/entitlements , including com.apple.security.cs.allow-jit (with no success).
I attached a full crash report with call stacks and reason of the crash. I myself would like know why and where exactly it crashes. I don't know how I can debug QtWebEngineProcess: it is launched silently in the background by QtWebEngine and crashes shortly after startup. четверг, 19 сентября 2019 г., 13:23:39 UTC+7 пользователь Jakob Gruber написал: > > Just a guess, since you mention notarization and the crash is in > GetDeoptimizationEntry (deopt entries are generated at runtime): did you > declare Allow Execution of JIT-compiled Code Entitlement > <https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_cs_allow-jit> > ? > > If that doesn't help, it'd be great to find out more about the crash. > Which part of GetDeoptimizationEntry > <https://cs.chromium.org/chromium/src/v8/src/deoptimizer/deoptimizer.cc?l=577&rcl=f1aa36df853b9956b46f3d792b59255c3b6fff46> > > crashes and how? > > On Thu, Sep 19, 2019 at 7:03 AM Dmitry Kravchenko <[email protected] > <javascript:>> wrote: > >> Hi! >> >> I'm developing an application with Qt 5.9.3 on macOS.
