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
