Details

I'm running Rockbox on a Sansa e250, with version r30618-110929.

After starting up a video from the file browser, pressing any button causes the player to lockup and show the error message "Data abort at 0005ff58 (0)". The only exception is the power button, which when pressed will bring me back to the file browser.

I have to hold down the power button and do a hard shutdown in order to restart the player.

I can reproduce this with other videos as well, but I tested with "elephantsdream-q6-224x176-469kbps.mpg".

I can reproduce this issue by putting the video on either the internal storage, or my SD card.

This behavior does not seem to occur in 3.9.1, but the bug has been in place for at least a day.
This task depends upon

Reason for closing:  Fixed
Additional comments about closing:  Presumably fixed. I'm not seeing trouble on any device in latest SVN.

Yes, that's definitely a new feature. Tried on Gigabeat S with similar results. I saw corruption in the fonts one time in the OSD just before it crashed.

Looks like the prophesies of the buflib beast are coming to pass. There's an antipattern present in the entire design that's going to be very difficult to repair.

I was trying on e200 and it wasn't crashing but no text was being drawn in the OSD.

I can still reproduce the original bug in r30623.

I noticed that sometimes when it froze with some videos I transcoded with VLC, the video still took up most of the screen, but the "Data abort" message was still being shown on part of the screen. The "ElephantsDream" video would show the "Data abort" message on the full screen, though.

Let me know if there's any other information that would help.

I've had this same problem since upgrading to r30619-110929 on e250. It only seems to appear when I have music paused or music queued up
with 'Resume Playback' turned on in Settings-General Settings-System-Start Screen menu or have just finished playing music. Tried selecting
'Main Menu' instead and problem only occurred while playing video after playing music. Playing video just after power-up but before playing
any music doesn't seem to exhibit problem.

I tried r30864 on my e260v1 and text display is now working. Does this seem resolved now?
