[PATCH] PR fortran/66942 -- avoid referencing a NULL C++ thing

[Steve Kargl]

When C++ was injected into trans-expr.c in the form of vec,
it seems whomever did the conversion to vec forgot to check
for a NULL C++ thing.  This patch seems to avoid the problem,
but having zero knowledge of C++ I could be wrong.

OK for trunk?

	C++ thing.
