My program simply :
   - Initialize a session.
   - Verify the remote server/key matching.
   - Test if pubkey authentication is ok for the remote server.
   - Create a private key from the file.
   - Calculate public key from the private key.
   - Offer this pubkey to the remote server.
   - Try to authenticate with this pubkey. And it failed here.

Hi Pierre-Yves,

Could you copy/paste the relevant part of your code ? It would help to
understand what can go wrong.

I went a little further in debugging and found that "packet_decrypt" in crypt.c returns a -1 before any logging on a malloc error trying to allocate a buffer of 0 bytes.

In the AIX documentation, i found that :
"If the size requested is 0, *malloc* returns NULL in normal circumstances. However, if the program was compiled with the defined *_LINUX_SOURCE_COMPAT* macro, *malloc* returns a valid pointer to a space of size 0."

So : libssh requires a valid pointer or not ? :)
