Bug#954651: gimp: Shrinking layer with cubic interpolation causes a segmentation fault

2020-04-28 Thread Bernhard Übelacker 
Dear Maintainer,
if it may be of any help, below is the backtrace from
the submitter, with line information manually added.

Could not find a complete match in upstream bugs, just one
mentioning OpenCL is not yet stable - is this still the case?

Kind regards,
Bernhard

Bug#954651: gimp: Shrinking layer with cubic interpolation causes a segmentation fault

2020-03-22 Thread Stuart Hayhurst 
Package: gimp
Version: 2.10.14-3
Severity: normal

I tried shrinking a layer from 256x256 to 128x128 with cubic interpolation
enabled, and the program crashed with a segmentation fault
