Using gdb, ignore beginning segmentation fault until reproduce environment segmentation fault

I use a binary name (ie polo) it gets some parameter , so for debugging normally i do this :
Quote:
1. gdb polo
2. run -e1 -o /var/bin
i wrote script for watchdog my app (polo) and check every second if it's not running then start it , the problem is , if my app , remain in state of segmentation fault for a while (ie 15 sec) , Watchdog would frequently and immediately , start the app (ie in 15 sec more than 10 times , it would start my app , and then again segmentation fault , again the watchdog script make my app start and son on ...) until i get crash in my environment which my stb get black screen and i have to restart my stb.
i already had fix that segmentation fault , but for next step , i also want to fix , the bug which cause my environment crash (since if in other part of my app , there was a segmentation fault , it shouldn't make my env crash which i have to restart every-time)
my question is , how could i debug , a application with watchdog script which is controlling my app , i mean , i could let that segmentation fault bug exists (for reproducing the env Crash (which i need to investigate) but the problem is before env would be crash , the segment-fault , happened , so it prevents my app to reach environment crash ,Would highly appreciated any idea.

CGI::Application::Dispatch::Regexp - Dispatch requests to CGI::Application based objects using regular expressions SYNOPSIS
use CGI::Application::Dispatch::Regexp; CGI::Application::Dispatch::Regexp->dispatch( prefix => 'MyApp', table => [ '' => { app => 'Welcome', rm => 'start' }, qr|/([^/]+)/?| => { names => ['app'] }, qr|/([^/]+)/([^/]+)/?| => { names => [qw(app rm)] }, qr|/([^/]+)/([^/]+)/page(d+).html?| => { names => [qw(app rm page)] }, ], ); DESCRIPTION
CGI::Application::Dispatch uses its own syntax dispatch table. "CGI::Application::Dispatch::Regexp" allows one to use flexible and powerful Perl regular expressions to transform a path into argument list. DISPATCH TABLE
The dispatch table should contain list of regular expressions with hashref of corresponding parameters. Hash element 'names' is a list of names of regular expression groups. The default table looks like this: table => [ qr|/([^/]+)/?| => { names => ['app'] }, qr|/([^/]+)/([^/]+)/?| => { names => [qw(app rm)] }, ], Here's an example of defining a custom 'page' parameter: qr|/([^/]+)/([^/]+)/page(d+).html/?| => { names => [qw(app rm page)] }, COPYRIGHT &; LICENSE Copyright Michael Peters and Mark Stosberg 2008, all rights reserved.
