That's a different bug (actually several different bugs). Ghostscript has a history of changing its security-related behavior around, and every time preview-latex stops working until another patch is committed to AUCTeX. Ghostscript 9.22 finally removed a security related feature (the .runandhide operator) without working secure replacement. A fix has already been committed to upstream AUCTeX: this was comparatively straightforward to do since preview-latex had in a previous iteration already removed security-relevant reliance on this operator in order to stop this game, but it had still relied on its use elsewhere. -- David Kastrup _______________________________________________ bug-auctex mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-auctex
