x509_write_cert_req() calls rsa_pkcs1_sign() without a random number generator. Then rsa_pkcs1_sign() calls rsa_rsassa_pss_sign() which rejects a call without a RNG with an error. Finally, the error is not checked in x509_write_cert_req(), leaving old buffer contents in the signature buffer.

Caused by not correctly initialized rsa_context. Works fine if rsa_context is initialized with RSA_PKCS_V15 as it should.
