Comment (by Andy Schmidt):

 Replying to [comment:20 dd32]:

 Just want to document MY scenario that was impacted by this bug.

 I was validating the correctness path to an external code base before
 storing that permanently as the "new" location.

 So I first confirmed a syntactically valid relative path, then the actual
 existence of a certain file there, then (in an overabundance of caution)
 had a try/catch with an "include" of that new codebase path followed by a
 function call. Can you tell - I didn't want to switch to a non-working
 path?

 Spent days trying to figure out which of my hooks/actions/filters/timing
 etc. might cause the "include" to have happened previously somewhere
 earlier in my code, before I stumbled across this bug report.

 Maybe the incident count is so low because it's so far-fetched and hard to
 pin-point; most people would just have to give up early and eliminate
 their (perfectly functioning!) code.
