Bug in intfgraphics.pas

[andre72]

I get a SIGSEGV exception when loading an image in:
intfgraphics.pas, line 4990. package LCLBase.

This occurs both in my own app _and_ in the image viewer example application (imgview).
The attached bitmaps of playing cards produce the error:  H02.bmp, C04.bmp
The more complex bitmap D13.bmp is loaded correctly (no error).

This freezes all attempts to convert my D7 app to Lazarus.

I am running Lazarus 1.0.14 under Windows 7, 64bits

Better post in bugtracker.

Had a bit of the same problem a few years ago.
I changed my images to PNG and everything was
working again, so i never looked at the problem ?
Maybe it was just lucky, but you should still follow
Leledumbo's advice though.

Thank you for your answers, they help.

I cannot login to the bugtracker, but will repeat my post as soon as I manage to do so.

How do I mark this issue as solved?

What's your code for loading it?

What's your code for loading it?

I cannot see any code here.

What I mean is, my questions here have been answered, thanks to you all.
The bug, I am afraid, is there.
I am testing the .png format. Currently not OK.

What's your code for loading it?

I cannot see any code here.

What I meant was: in your program: how do you load the image?
(Tipically there would be some Image.Picture.LoadfromFile call somewhere?)

I would like to test the image in Lazarus trunk, but I need to know by what means it gets loaded in order to reproduce.

@Bart: just tested with Lazarus image viewer according to bug report; added a note there. Thanks.

You beat me with the backtrace

Well... you can beat me with the solution  ....

especially as I'm looking into different stuff:

Meanwhile, I've got some sort of date reading capabilities in fpspreadsheet xls; need to test it with some more files... then on to date writing

[Bart]

Well... you can beat me with the solution  ....

I couldn't figure it out.
Every attempt I made ends in HeapTrc complaining e.g. "Marked memory at $0236BEC8 invalid".

@Bart, @BigChimp:

I don't know how to express it, but I stand awed by your support.
Cannot imagine why some card bitmaps crash the app, and a more complex, larger one loads ok.
Thanks

I have tested the issue with .png and ,jpg files, see the bugtracker.

Lazarus developer Marc fixed the issue in trunk. @Andre: please test with a recent version (e.g. a snapshot that contains the fix - see bug report) and mark the bug report resolved if it's fixed for you.

Just tested with your playing cards images & it works for me.

I am afraid I am not comfortable enough yet with Lazarus to do that right now.  I have however attached the full deck of cards which I am using for further testing should you require it.

FWIW:
First response after posting in the forum...: 3 hours.
Issue solved after posted in bugtracker.....: Five days.

I must repeat it: I stand awed by your commitment and support.
Kudos to you Marc, and to each and everyone of you all.

All's well that ends well and yes, thanks a lot to Marc and Bart.
