ap_verify runs ap_pipe with its default settings; i.e., ap_pipe aborts if it detects a version mismatch or a config mismatch. This is usually desirable, since ap_verify's purpose is to perform standardized, reproducible runs, but it causes problems when ap_verify is used for developer testing.

Consider adding support for the --clobber-config and --clobber-versions arguments, possibly enabled through a command-line argument in ap_verify.py rather than by default.
