I can reproduce the following crash:

Go to shuffle control and set:

"history size = max" (so playback will stop when every track has been played)
"save = yes"

Apply the settings on a playlist and wait until the last track has been played in "shuffle" mode (foobar now says "stopped").

Now exit foobar and a crash results. What's annoying most was, when I restarted foobar all my configuration settings (several hours of work!) were gone since the crash corrupts the config file!

Here is the failure report:

Version info:
foobar2000 v0.8.3
UNICODE

I think i reported this bug a long time ago. The person's response (don't know if he was the actual developer, but it seemed like he was) was basically 'golly, it shouldn't do that!' and then the thread kind of died. For this reason and others i've just stopped using the shuffle control altogether. :/


edit:
Yeah, here it is.

I've also reported this very bug a few months back without much happening. But I don't think Kode54 (the author) was able to reproduce, whitch makes it kind of hard to fix. But here I see at least two other people reporting the same. To repeat: Set history size to max, activate history saving & play the playlist in "shuffle" mode until it's finished (foobar2000 stopped - end of playlist). Then exit foobar2000 normally - you'll get a crash and a hanging foobar2000.exe process. Also foobar2000.cfg gets nuked - whitch is very annoying if you haven't got a backup. (Tip for Wolf71: Make a backup of config files after each modification - redoing 100.000 custom modifications are a pain in the ...)

Anyways: I haven't tested this for a long time; my solution was to reduce history size to approximately 99% - after that there's been no crash. Ofcourse this also means that it never reaches the end of playlist as it just wraps around when all files are played and continues (at history size max playback stops when all files in playlist have been played once).

Mine wasn't even set to maximum size and it still did that. I don't remember if it did it every single time, though. And i think once the play-back stopped you could prevent the crash by going into history preferences and resetting the history. (That's how i remember it, anyway. Try it out and see if it works.)

Anyway, at the time i just decided to write a batch file to copy my foobar configuration back over it whenever it crashed. Make a fix.bat and put in it: @copy C:\path\to\foobar2000.cfg.bak C:\path\to\foobar2000.cfg

(The path obviously depends on whether or not you've set it to have multiple users enabled.)

But yeah, if you absolutely must have shuffle, put that in system32 and Win+R 'fix' and that'll more or less work for you until the plug-in gets fixed, i guess....

I've only experienced this when history size was set to max. And then it was 100% reproducable on my comp. After reducing history size to 99% the problem went away. And I use shuffle all the time. Hmmm. Strange stuff.

My crash reports from back then BTW: here and here
