    Description

      Try opening the attached gif file in Qt Creator 6:

      qtrob@rob-desktop:~$ ./qtcreator-6.0.0-beta1o/bin/qtcreator -tcs ~/dev/src/qtqa/fuzzing/testcases/gif/oss-fuzz-22914.gif

      Creator will crash:

      qt.gui.imageio: QImageIOHandler: Rejecting image as it exceeds the current allocation limit of 128 megabytes
Segmentation fault (core dumped)

      The file was found by oss-fuzz triggering issue 22914 which was fixed in Qt 5.15.1 and higher.

      The same version of Creator built on Qt 5.15.2 instead of Qt 6.2.0 does not crash.
