libc.so (SIGABRT, SIGSEGV) about hermes

[tmikov]

@cnx-caiobarroso libhermes_executor.so is obviously related to Hermes, but it is not Hermes. Hermes is contained entirely in libhermes.so. libhermes_executor.so is a part of React Native and provides some additional functionality:

https://github.com/facebook/react-native/blob/3b6c522942ca1b3d3f5e2115e0a4e781063747d0/packages/react-native/ReactCommon/hermes/executor/HermesExecutorFactory.cpp

Besides, even libhermes_executor.so is not present in the second stack trace.

I see no evidence that this is caused by a bug in Hermes. I am curious to see the discussion in React Native that pointed you in this direction.

Two pieces of advice:

• By far the most common user mistake we see is people using Hermes simultaneously from two threads. If you can, make sure that isn't happening.
• You need a proper symbolicated stack trace to investigate this.

I am sorry, what makes you think that this is caused by Hermes? As far as I can tell, Hermes isn't even in the stack trace of the crashed threads:

@tmikov
I'm sorry for my lack of knowledge in the area, but isn't this hermes related?

libhermes_executor.so is a React Native library, so we unfortunately cannot provide much input here. RN may be able to help investigate this if you can obtain a symbolicated stack trace from that crash.
