Reproduced in Version: 7.2.0.0.alpha0+ Build ID: 8b3982681e98818388c09233960ad6eaacee205a CPU threads: 4; OS: Linux 5.7; UI render: default; VCL: gtk3 Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded Version: 5.2.0.0.alpha1+ Build ID: 5b168b3fa568e48e795234dc5fa454bf24c9805e CPU Threads: 4; OS Version: Linux 4.8; UI Render: default; Locale: ca-ES (ca_ES.UTF-8) Version 4.1.0.0.alpha0+ (Build ID: efca6f15609322f62a35619619a6d5fe5c9bd5a) This document contains an SVG path with 2699660320 elements. I'm inclined to say that the most useful thing we can do here is to simply return an error and say that we cannot process such a pathological document.
