Description John Waugh 2011-09-09 06:31:06 UTC
I updated from 3.3.13 to 3.5.11 (and later also tried 3.4.14), and whenever I try to connect, via smbclient for example, I get a core dump just after entering my password.

3.3 works just fine, so I have reverted to that.
Happy to provide more info though, if you can tell me what you want.

Example log info:

Comment 1 John Waugh 2011-09-09 06:47:31 UTC
I got 3.5 working by tweaking some 'make config' options.

In particular, for the non-working case, I had the following enabled:


In order to get it working, I turned on this (super)set:


It seems like either some options should not in fact be optional (in which case I should bug the port maintainer), or there is a bug in Samba.

I think this is not a problem with current versions.
