Pilot error on my side – doing three things in parallel
(fixing a patch, updating docs + attending a spec conference)
does not work well.
Unsurprisingly, when properly used, calling
c_parser_check_balanced_raw_token_sequence does work.

Hence, I removed my balanced function & only the OpenMP specific
omp_affinity function remains.

(Updated version attached.)

It looks as if one should/could update the gcc/cp/ function to use the same
algorithm as the gcc/c/ one – as the latter has also this issue. But that's
a separate issue and completely independent of this patch.

Thanks,

Tobias
