--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Thanks for filing this.
Reproducable with trunk. On trunk I also see similar behavior with the new
SARIF output format via options:
-fdiagnostics-format=sarif-stderr
-fdiagnostics-format=sarif-file
and with:
-fdiagnostics-format=json-file
With json output, the json::object for the error is being stashed for later
output here:
