I am using OpenSSL 1.0.0c and QtCreator IDE. Data signing routines report
success but EVP_VerifyFinal returns 0 (signature verification failure
according to the manual). When I try debugging the function always returns 1
(verification successful). When I change to invalid signature or another
public key the verification correctly fails. I've tried using 'sleep'
statements and testing it in a single thread - no effect: for valid
input EVP_VerifyFinal always returns 0 in release configuration and 1 during
debug.
