Let's say I have a subroutine that "dies". How can I determine what line called the subroutine? Debugger "Stack Trace" seems the obvious answer, but it does not work for me:
print "Hello\n";
a(0);
print "Middle\n";
a(1);
print "Goodbye\n";
sub a {
$parameter = shift;
if( $parameter ) { die };
}
bash> perl -d test.pl
Default die handler restored.
Loading DB routines from perl5db.pl version 1.07
Editor support available.
DB<1> c
Hello
Middle
Died at test.pl line 10.
Debugged program terminated.
DB<1> T
$ = DB::fake::at_exit() called from file
/usr/local/lib/perl5/5.6.1/perl5db.pl' line 2697
$ = DB::END() called from file `test.pl' line 0
$ = eval {...} called from file `test.pl' line 0
DB<1>
While it died at line 10, what line called the subroutine that died?

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).
