From fb7458f9dd1c87b52e54fc5bb882854676fd4384 Mon Sep 17 00:00:00 2001 From: Pino Toscano Date: Sat, 8 Feb 2025 19:24:33 +0300 Subject: [PATCH] Avoid unconditional PATH_MAX usage Forwarded: no Last-Update: 2020-04-19 Use a "safe" size in case PATH_MAX is not defined; in the end, this should not be used, as a allocating realpath() will be used instead.
