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 ? :)
