Subject: 28.0.50; etags stops processing with no reason
Date: Sun, 24 Jan 2021 14:55:40 +0100

Hello,


calling etags on the following file gives a wrong result. This is a
modified snippet from the GNU Mach sources.


  macro_call(, b)

  void
  test(void)
  {
  }


The result is


draft.c,16
macro_call(1,0


The first line is a macro call, not a definition, so it should not
appear at all in the TAGS file. And then the parsing stops so there's no
"test" in the file. Maybe the problem lies in the empty macro argument
or the missing semicolon?
