+Subject: [PATCH 1/4] valgrind-monitor.py regular expressions should use raw
+ strings
+
+With python 3.12 gdb will produce the following SyntaxWarning when
+loading valgrind-monitor-def.py:
+
+  /usr/share/gdb/auto-load/valgrind-monitor-def.py:214:
+  SyntaxWarning: invalid escape sequence '\['
+    if re.fullmatch("^0x[0123456789ABCDEFabcdef]+\[[^\[\]]+\]$", arg_str):
+
+In a future python version this will become an SyntaxError.
+
+Use a raw strings for the regular expression.
