[Patch, Fortran, OOP] PR 56266: ICE on invalid in gfc_match_varspec

[Janus Weil <janus at gcc dot gnu dot org>]

Hi all,

here is a small patch which fixes an ICE-on-invalid problem by simply
turning a "gcc_assert" into a MATCH_ERROR. I am aware that the
resulting error message ("Unclassifiable statement") is not the most
helpful one, but I couldn't come up with something better.

The problem is that "c(i)" is wrongly identified as a function call,
which is the best thing one can do at parsing time. But giving an
error message based on this (wrong) assumption will not be any more
helpful, therefore I prefer the "Unclassifiable statement".

Unless someone has a better idea how to treat this, I will commit the
attached patch as obvious.

Cheers,
Janus
