+    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.
