While I think that the TAP::Parser change is ill-advised, the behavior you see
with the dropped directories in @INC is nevertheless a bug in core Perl
(because calling Perl with the short pathname should not change the
functionality).
Could you try the attached patch to see if it normalizes the Perl behavior
regarding $^X and @INC again? If you can confirm that it works for you
then I'll commit it to blead, which means eventually we don't care anymore
if the problematic code in TAP::Parser gets reverted or not.
Don't expect this to go into 5.10.1 though; it is too late for that.
Cheers,
