FileZilla crashes while processing a queue

Reported by:	Jason Mount	Owned by:
Priority:	normal	Component:	FileZilla Client
Keywords:	crash queue	Cc:
Component version:		Operating system type:	Windows
Operating system version:	5.1.2600.5657

Description (last modified by Tim Kosse)

FileZilla Client 3.1.5.1
Windows XP MCE 2002 + SP3

The client crashes reproducably while processing a large queue. Every time I start running my queue when I come back to the system, it has crashed.

I couldn't locate any symbols for FileZilla.

I have attached a minidump, and I have a full process dump I extracted it from if you need it.

Unfortunately there are no debugging symbols, the binaries do get created using MinGW.

Can you reproduce the crash with older versions?

Can you reproduce the crash on a fresh Windows installation without any other third party programs installed? (Especially not firewalls)

comment:2 by Jason Mount, 15 years ago

Status:	moreinfo → new

I would really consider generating symbols.

Yes I was able to reproduce it with 3.1.1.1; it had the exact same behavior. I have been using filezilla for some time and haven't seen this problem, but I haven't had a queue this large before.

My Queue now has about 1200 4MB files, it started out as round 7,000 files. I have exported the queue and when it crashes, I restart and import again. It has processed anywhere from tens of files to several hundres of files before crashing.

I'm not running any third party firewalls. I have VMWare, I'll try to get a VM set up to test on a clean XP install.

Here is the crash analysis for 3.1.1.1:

I've created some test binaries with debugging symbols: http://filezilla-project.org/nightlies2/2008-11-15/i586-mingw32msvc/FileZilla_3_setup.exe
Since the executable is 88 MiB large, I hope you can understand why I usually do not include the debugging symbols, they are huge.

Note that the symbols are in a non-proprietary format Windows does not understand.

You need to run FileZilla using GDB: http://downloads.sourceforge.net/mingw/gdb-6.8-mingw-3.tar.bz2?modtime=1208982015&big_mirror=1
Extract the executable into the FileZilla directory and start it. Type the following:
file filezilla.exe
run

When it crashes, enter this:
bt

comment:4 by Jason Mount, 15 years ago

The executable was normal sized, I assume the correct URL is:
http://filezilla-project.org/nightlies2/2008-11-23/i586-mingw32msvc/FileZilla_3_setup.exe

I'm running it now.

comment:5 by Tim Kosse, 15 years ago

Ah sorry, you are right, the 2008-11-23 is the correct one.

This is the output of GDB:

I still have the gdb session open, so let me know what other commands to try. Sorry I'm not very proficient with GDB.

comment:7 by Jason Mount, 15 years ago

I managed to use a crash dump from Windows to get the stack and gdb to examine the symbols to get a picture of the crash. If you need more you can use gdb to explore the symbols your self.

Hopefully this will help.

How are you connecting to that server? Do you use the quickconnect bar or the site manager? In the latter case, have you set any non-default options for that site?

I originally used site manager, but I have been using the imported queue. Here is what I have, some fields are replaced with '*':

Nothing unusual in it.

Please try this build: http://filezilla-project.org/nightlies2/2008-11-24/i586-mingw32msvc/FileZilla_3_setup.exe

It contains even more debugging information.

Ridiculous large executable already at 190MiB. And yet I could still add more...

The same thing happened, no back trace:

Is this relevant?
http://lists-archives.org/mingw-users/11483-using-gdb-under-mingw-backtrace-stopped-framedidnot-save-the-pc-compilation-flags-and-compiler-version.html

It suggests that -gstabs be used when compiling.

Sorry, I got busy and didn't have time to test this. Is this still the version you want me to test?

comment:14 by Tim Kosse, 15 years ago

Yes.

comment:15 by Jason Mount, 15 years ago

I haven't been able to reproduce the problem yet, but even when I click "Crash" from the "Debug" menu, gdb still says "Backtrace stopped: frame did not save the PC", so I doubt reproducing the crash will yeild any useful information.

Is this a valid assumption?

Does this problem still happen with the most recent version of FileZilla?

comment:17 by Jason Mount, 14 years ago

Status:	moreinfo → new

No. I haven't seen this problem for several builds now.
