      Try sourcing the following script

      function Fu()
      throw 1234
      silent! call Fu()
      try|let b=au#xxx()|catch|echomsg v:exception|endtry

      . After you source it with “vim -u NONE -N -S script-name.vim” you will see

      Error detected while processing /tmp/zshubfJ7j:
      line 5:
      E117: Unknown function: au#xxx
      E15: Invalid expression: au#xxx()|catch|echomsg v:exception|endtry

      while expected to see just

      Vim(let):E117: Unknown function: au#xxx

      . If you replace “let b=au#xxx()” with “throw 1234” exception is caught as expected.

      Also note that “:silent! throw 1234” does not silence the exception.

      Note: while :try/:catch does not work after you experienced this problem you still may use :redir to get error messages silenced with :silent!.
