>Description:
	When a dependent library of the object being loaded is not found,
	dlopen() will core dump.

>How-To-Repeat:
$ cat foo.c
#include <dlfcn.h>

int
main()
{
        dlopen("/usr/pkg/lib/libgii.so", RTLD_LAZY);
}
$ cc -o foo foo.c
$ ldd ./foo /usr/pkg/lib/libgii.so
./foo:
         -lc.12 => /usr/lib/libc.so.12
/usr/pkg/lib/libgii.so:
         -lgg.0 => not found
         -lc.12 => /usr/lib/libc.so.12
$ ./foo
