hermes: Crash in RN debug mode

Appreciate this report probably isn’t too helpful as I don’t have a repro I can share, but I wanted to ask what’s the best way to debug an issue like this?

Crash happens in debug mode, React Native 0.60.3, Samsung Galaxy S9+. Context-wise, I suspect this is happening when loading ‘db’ files for react-native-local-mongodb (~15 files, tens to hundreds of lines per file, each containing a stringified JSON object).

Aside from that, Hermes seems significantly slower than JSC in debug mode (maybe 3 or 4x slower, stuff like switching routes with react-navigation takes a few seconds), is that expected at this stage? Could that be to do with the amount of console.log-ing we do, I know that’s a big issue with JSC on slower devices.

In release mode, the app startup is significantly faster with Hermes and general performance seems similar to JSC so it would definitely be nice to make the switch in future 👌

@HeribertoAlves that’s actually a different crash (due to a non-ASCII character in a string that says it should be ASCII). Can you file a separate issue for that and include that stack trace?

#47 done!

HeribertoAlves on Jul 17, 2019

This crash (“Too many handles allocated in GCScope”) is an assert we have enabled in the native code of Hermes, and its purpose is to find problems where Handles are allocated in loops:

for (int i = 0; i < something; i++) {
  runtime->makeHandle(HermesValue::encodeNumberValue(i));
}

Native code is supposed to either make a new GCScope, or use a “marker” and flush it every loop iteration, like so:

for (int i = 0; i < something; i++) {
  GCScopeMarkerRAII marker{gcScope};
  runtime->makeHandle(HermesValue::encodeNumberValue(i));
}

In order to fix this, we need to know what the native stack looks like. It should be possible to attach a native debugger (gdb or lldb) to Hermes running on Android and get the backtrace. It is usually a trivial fix for these types of crashes, once we know what native function it is happening in.
