Bizarre copy of ARRAY in sassign at C:/progfile/Perl-5.8.8/lib/Carp/Heavy.pm line 45.

This also manifests itself as: "panic: attempt to copy freed scalar"

Patch for Carp in case anyone is interested. Find the call to format_arg in Carp.pm or Carp/Heavy.pm (depending on version), and replace with (prefix @args with my depending on version also. E.g. in 5.8.8 it's "my @args" in Heavy.pm, in 5.14.1 it's just "@args" in Carp.pm):

@args = map { local $@; my $tmp = eval { Carp::format_arg($_) }; defined($tmp) ? $tmp : 'unknown'; } @DB::args;
And now instead of an unhelpful error message referring to a line in Carp, you'll get the stack trace you wanted, albeit with one or more 'unknown' arguments shown in the function calls.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
