problem printing enums as integers with dwarf2

[Kevin Nomura <nomura at netapp dot com>]

Before filing a bug I'd like to check if I'm missing
something obvious.  A C enum is defined with elements
x0, x1, ..., x999 starting at 0 and incrementing naturally
with no "=" reassignments.  It is compiled on Linux redhat 8
(for example) which uses dwarf2 by default: gcc -g enum.c

x129 is printed as an integer:

(gdb) p/d x129
$2 = -127

I expected 129.

Compile with stabs explicitly and get the expected behaviour:

[siml4]$ gcc -gstabs enum.c
[siml4]$ gdb a.out

(gdb) p/d x129
$2 = 129
(gdb) 

Here is a testcase generator in perl to declare the 1000 element enum.



#!/usr/bin/perl -w
use strict

print "enum e {\n";

for ($i=0; $i<1000; $i++) { printf "\tx%d,\n", $i }
print <<EOF;
};

main()
{
        printf ("%d\\n", x129);
}
EOF
