I think it might have to do with this: hashed_identifier_len = strlen("evopvr___") + strlen(user) + strlen(passwd) + strlen(host); hashed_identifier = (char*) emalloc(hashed_identifier_len); sprintf(hashed_identifier, "evopvr_%s_%s_%s", user, passwd, host); your emalloc() needs to add +1 to the allocated memory for the \0 at the end of the string of hashed_identifier. So the next emalloc call will allocate the spot where your \0 is so you just lost the end of your string of hashed_identifier. HTH, Curt -- "I used to think I was indecisive, but now I'm not so sure."
