Test suit cannot fork process for debugging with clamav.

Hello All,

I try to debugging test suite of Clamav. Test suite writes for
fork process in order to debug code. First step, Program started by
libtools that declare the gdb debug tool. After run programs. It's
represents error as below. I debug "fork_setup()" function in the main
function but show error SIGSEGV. It's show segmentation fault. How i can
debug a source code in another way? That's is source code of test suite
for fork process[https://gist.github.com/2651305].

$ ./libtool --mode=execute gdb -q
~/Clamav/unit_tests_checkfs/tests/.libs/check_cli_load
Reading symbols from
/san01/home/chatsiri/workspacecpp/Clamav/unit_tests_checkfs/tests/.libs/check_cli_load...done.
