Crash when downloading folders of files

[Aaron Whitehouse]

Hi,

I am using a fully updated Edgy and tried to download a folder containing folders and files off an ftp server. GFtp downloads the file/folder list and then crashes.

$ gftp
gFTP Warning: Skipping line 229 in config file: entropy_source
gFTP Warning: Skipping line 232 in config file: entropy_len
gFTP Warning: Skipping line 235 in config file: verify_ssl_peer
Segmentation fault (core dumped)

I will attach the core dump. I can't get a backtrace as there are no debug symbols available for this package. It is consistent so I can test whatever is needed.

Here is the core dump.

Instruction how to get debug symbols for all packages can be found here:
https://wiki.ubuntu.com/DebuggingProgramCrash.

It is possible that this crash happens due to those warning messages, so attaching that config file could be helpful too.

Changed to needs info. thank you.

Okay, I followed the "Old Notes" exactly and, after all that, I get:

gftp is a script which launches gftp-gtk applicaiton, so you have to run gftp-gtk instead when using gdb.

[Aaron Whitehouse (aaron-whitehouse)]

Ah... *blush*. Got you. Here it is. Interestingly, when running through gdb it hangs instead of crashing, but it seemed to give some useful output to gdb.

[Aaron Whitehouse (aaron-whitehouse)]

Here is the output from Valgrind.

$ valgrind -v --tool=memcheck --leak-check=full --num-callers=12 --log-file=valgrind.log gftp-gtk

I was very surprised, everything worked perfectly (obviously a lot slower than usual) when gftp was run in this way - there was no crash and no freeze.

[ville palo (vi64pa)]

Thank you, I'll think here is enough information about this. I'll mark this as confirmed.

[Sergio Uribe (sergiouribe)]

confirmed also in edgy...
attached is the crash info. BTW is the first time that gftp crashes in my system, and I use it a lot...

gftp version: 2.0.18
OS: Ubuntu 8.04 Hardy Heron

I still have the problem since Ubuntu 6.06. If I download many folders and
files at one time I only get a segmentation fault. Currently 193 folders and
4892 files.

Backtrace is attached.
