Maybe related.... The mother of all process is Zygote. An Android
Activity is effectively forked from it (some hand waiving).

Zygote loads a down level version of OpenSSL. It used to be 0.9.8, but
its an odd mix of 1.0.0 and 1.0.1 now. When your app attempts to load
its version of OpenSSL carried around in the JNI folder, its not
loaded because Zygote already loaded a down level version provided by
the platform.

So one of my first guesses would be a bug is present due to the way
AOSP supplies OpenSSL modulo the way the way Zygote works.
