      Description

      If a file is greater than 4094 bytes cfengine reports: ExpandAndMapIteratorsFromScalar called with invalid strlen

      Reproducing:

      > echo "">/tmp/data; for X in `seq 1 4095` ;do echo -n "x">>/tmp/data ;done
      > /tmp/3.5/var/cfengine/bin/cf-promises -f <(echo 'body common control {bundlesequence =>

      {"test"}

      ;} bundle agent test

      { vars: "test" string => readfile("/tmp/data", "81902"); }

      ')
      expand.c:286: ProgrammingError: ExpandAndMapIteratorsFromScalar called with invalid strlen

      This is using the binary and libraries from the i386 3.5.0rc-1 debian package.

      I suggest that 4K is far too small as a filesize limit. Can't the second argument to filesize() permit larger files?
