Package: bison++
Version: 1.21.11-3.1
Severity: normal

Hello maintainer,

when running bison++ (version 1.21.9-1) on an empty grammar file or
giving an invalid file name, it crashes:

  $ bison test.y
  "test.y", line 1: no input grammar
  "test.y", line 1: no input grammar
  *** Error in `bison': double free or corruption (!prev):
  0x0000000001442780 ***
  Aborted (core dumped)
  $ bison non-existing-file.y
  bison: non-existing-file.y: No such file or directory
  Segmentation fault (core dumped)
  $


Greetings,
        jn
