    Description

      When using
      /usr/bin/innochecksum Ver 10.6.14, for debian-linux-gnu (x86_64)
      I get "Floating point exception" error at end of output for the command

      /usr/bin/innochecksum -S ./ibdata1

      Floating point exception
      
      

      Testing against the same ibdata1 file against innochecksum that is provided with mysql 5.7.42 I do not get any error.

      I have seen this on two recent cases. ibdata1 file is attached.
