We are intending to advance the toolkit.shutdown.lateWriteChecksStage pref, to collect information (and crash on DEBUG) about writes which happen during and after the xpcom-shutdown-threads notification. This is producing failures in the PrintTargetPDF.cpp destructor because we end up calling write_func and writing to (I presume) the target PDF. This _feels_ like something we can just skip, so that's the review request I am sending, but please let me know if it's critical that we write to this file during shutdown.
