'Crash if bad config', abbreviated as 'cibc' (and handled by vf_cibVFCfg.cibVFCfg()), analyzes your vf-configuration, crashing with helpful information and diagnostics, when an error is detected. Cibc is critical in development, as you create your vf-configuration. In production, when you know your vf-config is perfect, you can sacrifice it in order to maximize speed and minimize client download (it can always be turned on via the vfpd-toolbar).

What is your favorite integer between 8 and 7?
Here is an example of what can happen when you don't use cibc, but should. The vf-configuration for this form is invalid. Specifically, iMinLength is greater than iMaxLength, meaning everything is considered invalid.

Activating CIBC

With the below value for the 'sb_cibcOnOff' parameter, for validate_form... ...then when VFP-Diagnostics are off, cibc is... ...and when VFP-Diagnostics are on, cibc is... When Recommended
...configVF() ...configVFPD() Downloaded Active Downloaded* Active*
CIBC_ON  CIBC_ON  true true true true During initial development, to protect you from carelessness.
CIBC_OFF CIBC_ON  false false true true When diagnosing a particularly difficult, although short-term, problem. This prevents you from having to click [Load CIBC] and then select 'CRSH' from its drop down each time the page reloads (as may happen when a crash occurs).
CIBC_ON  CIBC_OFF true true false* false*  
CIBC_OFF CIBC_OFF false false false* false* During production, once you're certain the form's vf-config is perfect.
