Hi,

I'm having a problem with pure-ftpd-ldap on amd64.

Short story: When trying to authenticate, the child crashes.


Slightly longer story:

I've had the same setup running for years on 32bit machines. The setup
comprises OpenLDAP + TLS and pure-ftpd-ldap + TLS, authenticating
against an OpenLDAP server on the same machine. I've now copied the
same setup to four different machines:

 4.4/i386 -> works
 4.5/i386 -> works (so it's not a 4.4/4.5 issue)

2x 4.5/amd64 (different hardware) -> breaks (so it's not a hardware issue)

All machines in question have ECC memory, and the amd64 machines have
different quad-core Xeon CPUs, one L5420, and one X3230. One of the i386
machines has older dual-core Xeon CPUs, the other has a P3.

The last (only) thing I can see in the logs is this:
Jun 14 17:19:11 bgp2a pure-ftpd[7398]: ([email protected]) [INFO] New connection 
from 193.221.127.48
Jun 14 17:19:11 bgp2a pure-ftpd[7398]: ([email protected]) [INFO] SSL/TLS: Enabled 
TLSv1/SSLv3 with AES128-SHA, 128 secret bits cipher

The crash happens immediately after the ftp client tries to actually
log in to the server.


I've tried to disable SSL/TLS on the FTP server, but to no avail, so
I'm inclined to suspect some 64bit issue. A little help to debug this
would be most welcome!


TIA!
