From 4a005f01e9ba4322bdb41631928ecc9edf51b189 Mon Sep 17 00:00:00 2001 From: Sebastian Harl Date: Wed, 26 Mar 2008 09:34:14 +0100 Subject: [PATCH] utils_cmd_{get,put}val.c: Fixed usage of parse_identifier(). This function modifies its first argument which, in these cases, is used again after the function call. Now, a copy of the string is passed to parse_identifier(). This is a backport of 0a905cbd3151716c5749b5e7c5e439861466804d.
