From 72fa5c63f80262019d807658cc537c9897c4b1d1 Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Fri, 18 May 2007 03:54:15 +0200 Subject: cache_safe_filename() needs more buffers The single static buffer makes it impossible to use the result of two different calls to this function simultaneously. Fix it by using 4 buffers.
