Comment (by sysrqb):

 It's interesting that running obfs4proxy in Tor Browser 9 on an x86
 Android emulator shows a different error for me (but still fatal):
 {{{
 - WARN: Managed proxy at '/data/app/org.torproject.torbrowser-
 mbH3STiraudHcuno3Pi09w==/lib/x86/libObfs4proxy.so' reported: runtime/cgo:
 pthread_key_create failed
 - WARN: Pluggable Transport process terminated with status code 6
 }}}

 I also hit an assertion failure in tor, but I'll come back to that later.
