Summary | 0032342: anchordocking crash | ||||
Description | So I took a first look at the anchordocking I dragged the object inspector and dropped it in the middle of the source editor, because I did not know what I was doing there. Then there was a window with two tabs, source editor and object inspector, which I did not like at all, so I dragged the object inspector back and dropped it on the leftmost side of Lazarus. Which caused the attached screenshot and this: [TJITComponentList.DestroyJITComponent] ERROR destroying component Error: Access violation Stack trace: $0000000000B054CD SETCUSTOMFORM, line 1165 of

Resolving. This is caused by a local FPC configuration issue. |
|
fpc caused the other issue This one happens with 3.0.0 too |
|
Well, it works for everybody else. Besides, I don't think FPC causes bugs in AnchorDocking. It is a configuration issue in your system. |
|
I personally don't think something like this can be caused by FPC or user configuration. There are issues reported about docked pages. Besides AnchorDocking shouldn't crash the IDE whatever the configuration is. |
|
Actually I can reproduce it now... [Edit] No, this is a different bug. I cannot reproduce the original bug. Lazarus compiled with FPC trunk for GTK2 widgetset breaks the docking completely. There is an Access violation after any docking operation. The output below shows a warning "TAnchorDockPageControl.Destroy with LCLRefCount>0". Why it happens only with FPC trunk? What changed? Can others reproduce? --- (lazarus:7359): GLib-GObject-WARNING **: gsignal.c:1207: no emission of signal "button-release-event" to stop for instance '0x4782110' TDockPerformer.DragStop Dropped False False AnchorDockSite8:TAnchorDockHostSite WARNING: TAnchorDockPageControl.Destroy with LCLRefCount>0.

I cannot reproduce any crashes now. Your test project also works without crashes. I guess things have been fixed. Resolving... BTW, you project has an ugly unit search path. I added newlines after ";" and it looks like this: U:/components/pascal/data; ../../import/synapse; U:/components/pascal/internet; U:/components/lazarus/dialogs; U:/components/pascal/system; /home/benito/hg/components/pascal/data/; /home/benito/hg/programs/contests/euler/; /home/benito/hg/components/pascal/internet/; /home/benito/hg/components/lazarus/dialogs/; /home/benito/hg/components/pascal/system/; /home/benito/hg/components/pascal/import/regexpr/source/ You should use packages for such library code! Adding the same paths to many projects can lead to problems. |
