gcc12-pr104623.patch
The problem is that the function purges the tokens, from the token after
CPP_PRAGMA until CPP_PRAGMA_EOL (the latter inclusive). But CPP_PRAGMA is not
purged. So, next time we tentatively parse it we ICE because CPP_PRAGMA isn't
followed by CPP_PRAGMA_EOL anymore (because purged tokens are ignored).
I have tried various things, purging also the pragma_tok token or changing
second argument of cp_parser_skip_to_pragma_eol to NULL in
cp_parser_skip_to_end_of_statement and
cp_parser_skip_to_end_of_block_or_statement but both regressed various
testcases.
This at least in quick check-g++ testing didn't regress anything.
