Android - Fatal crash 'signal 11 (SIGSEGV), code 1 (SEGV_MAPERR) strcmp'

I am using 'mobile-ffmpeg' from here in one of my android project. Recently I'm seeing a lot of native crash as following:

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
strcmp

Stacktrace:

*** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
pid: 0, tid: 0 >>> com.example.myapp <<<

backtrace:
  #00  pc 000000000007f758  /apex/com.android.runtime/lib64/bionic/libc.so (strcmp+24)
  #00  pc 00000000002d3b10  /data/app/com.example.myapp-BkrKS2bGJO8lBYjvIITTkw==/lib/arm64/libavcodec.so

I am completely clueless about how to debug this.
