Package: lftp
Version: 4.6.0-1+deb8u1
Severity: important
Dear Maintainer,
After upgrading to Debian jessie, the packaged version of lftp seems to
occasionally crash with segmentation faults or assertion failures.
My use of lftp is invoked by a script and run without a terminal, with the
following sequence of commands passed via lftp -f
get http://url/1/1mb.ts &
get http://url/2/1mb.ts &
get http://url/3/1mb.ts &
(repeated around 15 times with different URLs)
wait all
exit
The URLs are to MPEG TS (HLS) segments which do not last more than a
minute, so I cannot include them here. It is possible that the HLS
segments are being deleted mid-transfer if this aids in reproduction.
Under Debian wheezy, lftp when invoked with the same script never once
segfaulted or otherwise failed.

I was unable to find a debug symbol package to get better debugging
information. If you could advise on how to improve the debug output I
can perform any necessary steps.
