+Request CTF debug information and use level to specify how much CTF debug
+information should be produced. If -gt is specified without a value for level,
+the default level of CTF debug information is 2.

+Level 0 produces no CTF debug information at all. Thus, -gt0 negates -gt.
+
+Level 1 produces CTF information for tracebacks only. This includes callsite
+information, but does not include type information.
+
+Level 2 produces type information for entities (functions, data objects etc.)
+at file-scope or global-scope only.
