rharrison@ can you take a look? More fuzzer image decoder timeout fun.

Looking at a profiling run, the execution is being dominated by a single pass of fetching pixels and performing a calculation based on them. Given that the input image/canvas size is specified as something like ~32k x 10k, this means there is just a lot of operations that need to be run. Given enough time the fuzzer completes without issue. I don't think there is much for us to do, unless we have an expert on JBig2 that might know how to avoid this step.

ClusterFuzz testcase 5021905434968064 is still reproducing on tip-of-tree build (trunk). If this testcase was not reproducible locally or unworkable, ignore this notification and we will file another bug soon with hopefully a better and workable testcase. Otherwise, if this is not intended to be fixed (e.g. this is an intentional crash), please add ClusterFuzz-Ignore label to prevent future bug filing with similar crash stacktrace.
