+Subject: [PATCH] Fix buffer overflow in Backup.Creator
+
+I noticed that while testing the upcoming GCC 12 with -D_FORTIFY_SOURCE=3:
+here I have
+
+$1 = 0x7ffff7f0f940 <Buffer.1.lto_priv.1> "Linux, kernel 5.16.14-1-default (#1 SMP PREEMPT Fri Mar 11 12:33:34 UTC 2022 (80acc65))"
+(gdb) p (int)strlen(GetOS())
+$3 = 87
+so GetOS() returns 87 chars while:
+
+include/gammu-backup.h: char Creator[80];
