crashes on resizing image

ArtPaint-3285-debug-27-06-2025-15-43-38.report.txt

whenever I try to resize this image, ArtPaint crashes with the attached stacktrace.
Using Haiku nightly 58936 and Artpaint 2.7.1

I've tried with a few images, but didn't get it to crash... That's on beta5 though.
Any special settings, like non-locked aspect or filtering? Does it crash with all images or just one particular or all of a specific size? Can you upload an example image?

[grexe]

just tried again with this image, no special settings or filters, just "resize canvas".
Using latest nightly hrev59041 and ArtPaint 2.7.1.

Aha. Du musst im frühern Leben wohl a Reblaus gwesen sein... :)
Unfortunately, I still cannot crash ArtPaint with this image. Neither on Beta5 nor a recent nightly...

i am trying to fix #664 so i downloaded this image for testing and i can get it to crash. it didn;t at first but now all i have to do is open artpaint open this image and in resize i hit x2 and then ok and it crashes. no promise but since im looking at scale code anyway maybe i can figure it out

[humdingerb]

Ha! As it's a rather huge test image, I always decreased its size when resizing before. Enlarging x2 does indeed crash. With a debug build the Debugger points to https://github.com/HaikuArchives/ArtPaint/blob/master/artpaint/Utilities/ScaleUtilities.cpp#L40 .

Good hunting! :)
