Hang / endless loop trying to unpack some Android firmware

While unpacking a certain firmware file that you can find here I discovered that recursive unpacking with binwalk -eM would hang: https://firmware.center/firmware/Motorola/Android/XT1650%20Moto%20Z%20%28Griffin%29/Stock/XT1650-03/XT1650-03_GRIFFIN_RETEU-EMEA_MPL24.246-17_cid50_subsidy-DEFAULT_regulatory-03_CFC_EMEA.xml.zip

I tried tracking this down to a reduced test case. It's, however, still 700 MB (37MB compressed). Cannot upload due to Github's size limit, will provide it here for a while: https://files.hboeck.de/binwalk-endlessloop-testcase.tar.xz
