An issue was discovered in Poppler 0.74.0. There is a NULL pointer dereference in the function SplashClip::clipAALine at splash/SplashClip.cc. Reference: https://gitlab.freedesktop.org/poppler/poppler/issues/748
Created poppler tracking bugs for this issue: Affects: fedora-all [bug 1696640]
Unable to reproducer this on any version of Red Hat Enterprise Linux. Prints quite a bit of junk, but no segfault/valgrind warnings or anything else suspicious. Guessing introduced in a later upstream version.
