CallStack is not output at crash in Android project

CallStack is not output at crash in Android project

UDN
Description

In an Android project that intentionally crashes from C ++, the call stack is not output at the time of the crash.

Perhaps the function that outputs StackTrace in DefaultCrashHandler of AndroidMisc.cpp is not called with an error.

As far as I have investigated, it seems to fail in the last FCStringAnsi :: Strncat (HumanReadableString, StackLine, HumanReadableStringSize); in FAndroidPlatformStackWalk :: SymbolInfoToHumanReadableString.

Steps to Reproduce
  1. Open repro proj
  2. Create android package and deploy to android device
  3. Run the package on device
  4. Crash
  5. Check log

expect : output callstack in log
result : there are not output about callstack in log
