^^^ BTW: note that this leak is different from the one you initially 
reported: this is related to a call to ldap_alloc_ber_with_options() 
while the initial one was related to a call to ber_memcalloc_x() 
occurring in the same function but quite few lines later, in a totally 
different context.  I carefully reviewed the code and there seems to be 
no chance of leaking within the try_read1msg() function; it's quite 
likely that the leak occurs somewhere else much later, during the usage 
o the response messages, as a consequence of some very tricky and hardly 
reproducible conditions.
