The hermesFatalErrorHandler should log the message it received into Logcat. Are there any more lines in the log before the process was killed with SIGKILL?

Having the same issue, but only on non-debug builds.

[dulinriley]

@tarasvakulka can you explain why you closed the issue?
Is the problem gone?

If you can, please provide some context here about how it was resolved so that anyone in the future with this issue will know what they should do.

[tarasvakulka]

@dulinriley, problem was not in hermes, my method array sort worked incorrect and hermesvm throw error, I refactor my code and now my problem solved

[Awaisqr]

I am facing this same issue, if hermes is disabled in android/build.gradle then my app works fine but if hermes is enabled then I get error after splash screen "maximum call stack reached, js engines hermes". Note: I have also run gradle clean

[jasonalmaturner]

It should be noted that there is a bug with the array sort function in Hermes. https://github.com/facebook/hermes/issues/95

I had an issue where my comparator callback function in an array sort was incorrect. JavaScript engines usually fallback to the default implementation in that case, but Hermes doesn't and gets stuck in an infinite loop. Pretty understandable bug on Hermes' part, especially considering how new it is. Fixing my comparator function solved the issue for me.

[tarasvakulka]

@jasonalmaturner You are right, this is bug of Hermes, I hope Hermes team fix this in future, because I spent a lot of time to find this problem in infinity loop if Hermes is on

[tmikov]

@tarasvakulka we realize that this is a problem and we are working on fixing it. Unfortunately it isn't a simple fix, but we will address it. Thank you for your understanding!

I build my app bundle for Play Store with Helmet and only shows the splash, after crash.
