From alphavax@gmail.com on 2012-07-30 16:10:13:

Hello,

I'm having problems while debugging my program using the following
configuration:

  • Windows 7 64 bits
  • ActivePerl v5.14.2 for MSWin32-x64-multi-thread
  • Eclipse SDK Version: 4.2.0 Build id:
    I20120608-1400
  • EPIC - Eclipse Perl Integration Version: 0.6.44
  • PadWalker Perl Module Version: 1.94
  • DateTime Perl Module Version: 0.76
  • DateTime-TimeZone Version: 1.46

I'm able to see and trace my variables until I use the DateTime Perl Module:

sub gensqlscript
{
use DateTime;
my $dt = DateTime->now;
$dt->set_time_zone( 'America/Chicago' );
         print OUT "/****** Object:  StoredProcedure
[dbo].[$sp_hash{$x}{'Nombre'}]    Script Date: ".$dt->mdy('/')."
".$dt->hms." ******/\n";
         .
         .
         .
}```


After executing the $dt->set_time_zone( 'America/Chicago' ); line the
debbuger stops working and shows this message in Eclipse's Variable view:
"An error occurred while dumping array content; contents of the Variables
view may become invalid".

The log file of Eclipse shows this error:

What I'm doing wrong?
Is it valid to call $dt = DateTime->now; and then  $dt->set_time_zone(
'America/Chicago' ); same error happens if I use the following :

use DateTime;
my $dt = DateTime->now( time_zone => 'America/Chicago' );

I "Solved" this problem with the debugger temporarily using

use DateTime;
my $dt = DateTime->now( time_zone => 'floating' );

There's a lot going on here and I'm not sure what the problem is. It could
be in your code, it could be in DateTime, it could be something in the
environment.

I honestly have no idea what the problem is. I've never used Eclipse or
EPIC.
