This testcase had three dg-error tests for ".*<message>.*". But since . matches \n in Tcl regexps, the first dg-error ate all the output, leaving the other two to fail.
The regexp is eventually embedded in a larger one, so we can't prefix it with (?n). But the .*s aren't necessary, since dg-error tests for a partial rather than a full match. Tested on aarch64-linux-gnu & pushed as obvious.
