           Summary: Deep recursion in CGI::Carp::warn
           Product: Fedora Core
           Version: fc4
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: normal
         Component: perl
        AssignedTo: jvdias redhat com

Description of problem:
CGI::Carp::Warn experiences deep recursion when hit, followed by a segmentation
fault. This can make developing any web applications using CGI::Carp::Warn
difficult, as any trivial warning will cause pages of log output followed by a
crash.

See https://rt.perl.org/rt3/Ticket/Display.html?id=36521 for details and
possible patches.

Version-Release number of selected component (if applicable):
perl-5.8.6-15

How reproducible:
Always

Steps to Reproduce:
Execute script:
#!/usr/bin/perl

use CGI::Carp qw(fatalsToBrowser);
use diagnostics;

warn "foo";

Results:
Deeply nested warning message followed by segfault.
