--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Confirmed with GCC 9 + trunk/10
(Works with GCC 7, GCC 8 I have not tested it with.)

Seems to be a scoping issue of the hidden function-result variable:
The middle end complains that it sees the local variable declaration of the
contained function 'createVarnames' in the scope of the parent program
'stringtest'.
