oops, try this:

---

diff --git a/gsm_conf.c b/gsm_conf.c
index 560d9b3..6daf9b3 100644
--- a/gsm_conf.c
+++ b/gsm_conf.c
@@ -12,7 +12,7 @@
#include "main.h"

-char *gsm_conf_error = (char *)"";
+char gsm_conf_error[128] = "";

/* read options
*
---

i never had an error in the config, so an error message never created.
