Hello list, we are using the libssh2 v1.4.3 (with openssl 0.9.7m) since a while and try now to update to the current libssh2 v1.8.0 (with openssl 1.1.0c).
Each time when I try to make a connection to the SFTP-Server we get an null-pointer exception by reading. Here the call-stack for the sake of completeness: ---------------------------------------------------------------------------------------------------- Unhandled exception at (0x806505a8) 0x0064F5A8 belongs to _EVP_DigestUpdate (libssh2:digest.obj) ==[Register dump]== eax = 0000000000 ebx = 2432032460 ecx = 2432084620 edx = 0000000021 esp = 0x90f55d6c ebp = 0x90f55de8 esi = 0x90f6aa7c edi = 0x90f6aa8c eip = 0x806505a8 ==[Stacktrace]== [0] called from (0x8064a1f9) 0x006491F9 belongs to _kex_method_diffie_hellman_group_exchange_sha256_key_exchange (libssh2:kex.obj) [1] called from (0x8064a3db) 0x006493DB belongs to __libssh2_kex_exchange (libssh2:kex.obj) [2] called from (0x8064397c) 0x0064297C belongs to _session_startup (libssh2:session.obj) [3] called from (0x80642fa7) 0x00641FA7 belongs to _libssh2_session_handshake (libssh2:session.obj) [4] called from (0x802c7c8d) 0x002C6C8D belongs to ?Connect@CSSHClient (SSHClient.obj) [5] called from (0x8031e95c) 0x0031D95C belongs to xxxxx [6] called from (0x802df20b) 0x002DE20B belongs to xxxxx [7] called from (0x802dfab7) 0x002DEAB7 belongs to xxxxx [8] called from (0x802df16a) 0x002DE16A belongs to xxxxx [9] called from (0x802b7637) 0x002B6637 belongs to xxxxx ---------------------------------------------------------------------------------------------------- However, before the (EVP_MD_CTX *) ctx parameter becomes null after calling libssh2_sha256_init (here function EVP_DigestInit returns with 0). What I am doing wrong or is missing? Best regards Impressum/Imprint: https://www.ipetronik.com/impressum
