Hi,
My name is Arkady and I try to use Ptrcheck tool of valgrind .
My OS:
Linux chip.pineapp.com 2.6.20.21-Surf-SeCure #10 SMP Mon Jan 5 13:49:59
GMT 2009 i686 pentium4 i386 GNU/Linux
Valgrind version:
valgrind-3.5.0
The command is
valgrind --tool=exp-ptrcheck ./surf_http_proxy
surf_http_proxy is the my daemon and it have to run *forever.* But
Valgrind exit almost *immediately* with following output.
==5516== exp-ptrcheck, a heap, stack & global array overrun detector
==5516== NOTE: This is an Experimental-Class Valgrind Tool
