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.
