Category: 41. Photo Images Group: current: 8.5.2 Status: Closed Resolution: Duplicate Priority: 8 Private: No Submitted By: Jeff Godfrey (jgodfrey) Assigned to: Joe English (jenglish) Summary: Fatal Error in Wish Initial Comment: The following code will produce a fatal error in Wish (Windows XP, Tcl/Tk 8.52, Tile 0.8.2), when the window is resized.

Grab the right edge of the window and drag it narrower. Once the right-most button's entire image is obscured, wish crashes with the following error dialog: --------------------------- Fatal Error in Wish --------------------------- unable to alloc 4294967232 bytes --------------------------- OK --------------------------- Interestingly, changing the image to non-PNG-based data does not appear to cause the crash. Also, it occurs whether using tkpng or img::png. Jeff ---------------------------------------------------------------------- >Comment By: Daniel A. Steffen (das) Date: 2008-06-20 16:31 Message: Logged In: YES user_id=90580 Originator: NO I cannot reproduce either of those crashes on OSX (donal's img crash or the original ttk crash) using tk HEAD and tkimg HEAD from svn. Possibly the teapot Img is based on older sources? Donal, can you elaborate which parts of the OSX build get in your way? e.g. framework building is a completely optional (and non-default) configure option... ---------------------------------------------------------------------- Comment By: Jeff Godfrey (jgodfrey) Date: 2008-06-19 19:56 Message: Logged In: YES user_id=113550 Originator: YES > Since you are using Tk 8.5, can you remove the tile 0.8.2 and retest? Removing the [package require tile] results in the same crash. It seems that ttk widgets cause the crash while Tk widgets do not. ttk::button - crash ttk::label - crash button - no crash label - no crash Jeff Godfrey ---------------------------------------------------------------------- Comment By: Donal K. Fellows (dkf) Date: 2008-06-19 11:42 Message: Logged In: YES user_id=79902 Originator: NO I could believe that is a different bug too. I can't chase it though; the extra stuff das has added to the OSX build for Tk (framework building, etc.) gets in the way. ---------------------------------------------------------------------- Comment By: Joe English (jenglish) Date: 2008-06-19 06:17 Message: Logged In: YES user_id=68433 Originator: NO Duplicate of #1967576 (fixed in CVS 2008-05-23). This report: > Crashes at image creation for me on OSX with ActiveTcl 8.5.2.0.284846 and > img::png 1.3 out of the teapot. sounds like a different bug. ---------------------------------------------------------------------- Comment By: Jeffrey Hobbs (hobbs) Date: 2008-06-18 19:52 Message: Logged In: YES user_id=72656 Originator: NO Since you are using Tk 8.5, can you remove the tile 0.8.2 and retest? If only ttk::button is causing it, I suspect that there may be some request for an invalid height image. ---------------------------------------------------------------------- Comment By: Jeff Godfrey (jgodfrey) Date: 2008-06-18 18:23 Message: Logged In: YES user_id=113550 Originator: YES As I'm getting the same crash using many different images, I assume the image data is not the culprit. Also, using the sample code provided in this ticket, I don't get the crash if I use a standard Tk button as opposed to a ttk::button.

Fellows (dkf) Date: 2008-06-17 12:20 Message: Logged In: YES user_id=79902 Originator: NO Crashes at image creation for me on OSX with ActiveTcl 8.5.2.0.284846 and img::png 1.3 out of the teapot. No Tile, no widget creation. Suspect that there's either a bug in PNG loaders or the image is bad. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=112997&aid=1995663&group_id=12997 |
