error type in core.p4 not saved in parser symbol table?

[hanw]

Is the P4 error type saved in symbol table during parsing?

error { NoError , ... }

I am getting a few error messages when I try to run add a second unit test to the same gtest file.

(null)(5): error: NoError: Duplicates declaration NoError
 error {     NoError,     PacketTooShort,     NoMatch,     StackOutOfBounds,     OverwritingHeader,     HeaderTooShort,     ParserTimeout }
             ^^^^^^^
(null)(5): error: PacketTooShort: Duplicates declaration PacketTooShort
 error {     NoError,     PacketTooShort,     NoMatch,     StackOutOfBounds,     OverwritingHeader,     HeaderTooShort,     ParserTimeout }
                          ^^^^^^^^^^^^^^
...

The problem is not because of existing entries in symbol table, which are already cleared with a clear function to remove all entries in symbol table after each run.
