OEMCrypto was being initialized on session creation. Calls to
get property information may occur before any sessions are
created. This resulted in calls to OEMCrypto before a call to
OEMCrypto_Initialize which caused a segfault.
OEMCrypto initialization is now verified before any other calls are made.
Unit tests have been modified to verify that this indeed works.
