Re^4: Segmentation fault with HTML::TagParser module

Thank you shmem, for your valuable suggestion.
1) When I tried debugging(used print statements) in my script it got terminated with Segmentaion Fault after the HTML::TagParser instance is called . So, in HTML::TagParser module, I got the segmentaion fault in its parse sub routine.
2) The output of using gdb debug is given below.

(gdb) run burst_spider.pl -s "http://technologyreview.com/aggregates.a
+spx?p=1" -toolbar
Starting program: /usr/bin/perl burst_spider.pl -s "http://technologyr

Produce a backtrace with the gdb 'bt' command. At this point, seeing some code of yours would be helpful to help, too. But not the whole bunch - a minimal version which exhibits the same problem.	[reply]

Shmem This error seems to be occuring when we Parse the web page. The code from where we are getting the error is mentioned below : `my $html_local = HTML::TagParser->new($local_content); my $ele = $html_local->getElementsByTagName("title"); # get element + by title tag` [download] The $local_content is the entire content of the web page which we are crawling.
