in thread How to access the contents of a specific memory address?

my $address = 5; refaddr( \$address ); my $new_address = \$address; $$new_address = $$new_address * 4; sigqueue( $$, &POSIX::SIGRTMIN, $address ); $thr->join(); print Dumper($address); my $smash = unsmash_sv( 0 + $address );
I can't understand what you are doing here. times 4? "(char *) 5" will of course crash, so will "(char *) 20". If you use Windows, learn what WONT seg fault, Virtual Memory Map Viewer (FOSS I think) and VMMAP more advanced.
