Can you point me to the ftp server that caused the problem so I can replicate.

Alternately try to get a backtrace
(http://www.gentoo.org/proj/en/qa/backtraces.xml)

The segfault appears with any ftp with SSL enabled

(In reply to comment #2)
> The segfault appears with any ftp with SSL enabled

Please name one. I'm finding it a bit find to get one.

(In reply to comment #3)
I've configured one ftp server for you ;)

try it, lftp -u daniel,black -p 1337 nicoHQ.org.

You should get something like that:

WITH gnutls:
nico@multivac ~ $ lftp -u daniel,black -p 1337 nicoHQ.org
lftp nicoHQ.org ~ > ls
Violaci

That I did as per cced email. Reported upstream. Nonstripped stuff even enables
decent backtracks. Shouldn't be too long for a fix. Alexander is usually very
quick with fixes.

patch added to net-ftp/lftp-3.5.2-r1

Much appreciate the test server and bug report.

guessing it worked for you?

(In reply to comment #7)

Negative, now lftp doesn't crash with a segfault but commands like ls or mirror
doesn't work, lftp enters in a infinite loop with the message "Delaying before
retry".

Test server is working if you want to test it

I put this down to the test server being disabled - it doesn't respond to a SYN
packet. Please check.

(In reply to comment #9)

This is a different bug so please do a separate bug report in future.

Does this occur with MAKEOPTS=-j1? Does this error occur every time?

Sorry, due to several hardware problems on my machine the test server was
unreachable this weekend, now it's working :)
