[Expectperl-discuss] Perl debugger hanging after expectperl spawn in 5.8.0

[Joerg B. <jb...@MI...>]

Unter perl-5.8.0, the perl debugger is hanging after
issuing the spawn command in the perl test script shown below
(called from a terminal window with perl -d).
Under perl-5.6.0, debugging the same script works fine.

The script was tested using Redhat Linux 8.0 (Intel i386) and
Redhat Advanced Server 2.1 (Itanium 2) with this result.

Under Solaris 8, debugging works with both perl-5.8.0 and perl-5.6.0 .

Since we are migrating to perl-5.8.0, it would be nice to have the
full debugging capability also under this version.

Perl test script:

use strict;
use Expect;

$Expect::Debug=2;
$Expect::Exp_Internal=1;


my ($exp_fwatch);
my ($s_sys) = "bash";

$exp_fwatch = new Expect();
$exp_fwatch->raw_pty(1);
$exp_fwatch->spawn($s_sys);

# this part is not reached if perldb is hanging
print "after expect spawn\n";
