Predator and CL could not provide any possible suspects. Using the code search for the file, “layoutblockflow.cpp” assigning to concern owner from GIT revision log.

I don't think this is my fault, but maybe someone who has access to Windows could confirm. I cannot reproduce this in Linux, at least.

ClusterFuzz testcase 4711417415729152 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.
