XnViewMP 0.50

Post by svlasov »

  • "Auto image size" upon "/" key doesn't work anymore. Works fine on version 0.39.
  • Crashes when changing images too fast. E.g. if I scroll with wheel (mouse wheel set to next/previous) or PgUp/Down quick enough.

    Code: Select all

Which mode doesn't work??

If you go slowly, no crash?

I'm just trying out this software today, and am utterly impressed with its speed, even on my slower computer. Thanks for all the hard work!

I'm experiencing what sounds like the same issue, namely crashing with the "*** glibc detected *** /opt/xnviewmp/XnView: double free or corruption (out)" error when doing certain things fast. I've experienced the problem on three separate actions, although I can only remember one right now: changing the amount of info displayed with the thumbnails (i.e. Thumbnail, Thumbnail + Labels, etc.).

I can do some more testing, but would like to know what info would be most helpful to you first. I'm off to bed for today. :)

To my understanding pressing the "/" key should switch between different "Fit image to window ..." modes but it does nothing. For example if the image size is bigger than the window size and the image is scaled to actual size (1:1) then by pressing "/" in version 0.39 the image would get scaled to fit the window, in 0.50 version xNview doesn't react to "/" key at all.
[*] Crashes when changing images too fast. E.g. if I scroll with wheel (mouse wheel set to next/previous) or PgUp/Down quick enough.
Ubuntu 11.04 i386.

Yes, it doesn't crash if I switch images slowly. Looks like a race condition when freeing memory twice after it's been freed already.

I can't reproduce, with a clean xnview.ini? Only picture files in this folder? JPEG?

Only PNGs in the dir. I removed ~/.xnviewmp which was recreated again, still crashes.

Found another bug. For some images in the View mode they look horizontally flipped, but fine in the Browser mode. As an example it happens also for png icons that come with XnView.
