print: unexpected gawk's behaviour in case indirect function call

[Denis Shirokov]

Hi Gawk Team!

i found strange gawk's behaviour that is completely makes me crazy

example:

      BEGIN{

            print "DIRECT:   "      match( a, b )


            f = "match"

            print "INDIRECT: "      @f( a, b )


            print "END" }

output:

      D:\CPU\DEV\PROJECT\XASM>gawk -f ./a.txt
      DIRECT:   1
      match1
     < 'match' ??? wtf?
      END

it's looks like it's lost leading "INDIRECT: " string and then outputs
content of the
globvar `f: "match" and THEN indirectly call built-in match() function
and output it's
result.

please note that this behaviour was found while reporting about
another gawk issue that's will be reported soon. the provided example
is from there,

Windows 10(x64)
GNU Awk 5.1.1, API: 3.1 (GNU MPFR 4.0.2, GNU MP 6.1.2)

Kind Regards
Denis
