+Bugfix
+ * Ensure that calling mbedtls_rsa_free() twice is safe. This happens
+ when some Mbed TLS library functions fail. Such a double-free was
+ not safe when MBEDTLS_THREADING_C was enabled on platforms where
+ freeing a mutex twice is not safe.
+ * Fix a resource leak in a bad-arguments case of mbedtls_rsa_gen_key()
+ when MBEDTLS_THREADING_C is enabled on platforms where initializing
+ a mutex allocates resources.
