Re: [bug-gawk] Problem with array index in connection with "sorted_in"

[Nelson H. F. Beebe]

Christian Schneider <address@hidden> reports unexpected
output from gawk 4.1.1 (Debian 8) for this test:

        echo -ne "1.0\n2.0\n" | gawk '
          BEGIN {
            PROCINFO["sorted_in"] = "@ind_num_asc"
          }
          {
            A[$1] = 0
          }
          END {
            for (I in A) B[I] = A[I]
            for (I in B) SCRATCH = A[I]
            for (I in A) print I
          }'

The expected output is

        1.0
        2.0

but gawk 4.1.1 (Debian 8) reported

        1
        1.0
        2
        2.0

I just ran a test on Solaris SPARC with 86 versions of gawk from 3.0.0
to 4.1.3h, including 4.1.1, and all gave the expected output.

I also ran a similar test on CentOS 6 (== RedHat 6) on x86-64, with 84
versions of gawk, and got the expected output on most of them.
However, for these versions

        4.0.73
        4.0.74
        4.0.75
        4.0.76
        4.1.0
        4.1.0e
        4.1.0f
        4.1.0h
        4.1.1
        4.1.1b
        4.1.1c
        4.1.1d
        4.1.2
        4.1.3
        4.1.60

I got the erroneous output that Christian reported.  Thus, I conclude
that (a) the bug is fixed in the latest versions 4.1.3g and 4.1.3h,
and (b) the bug is platform dependent.
