As I said, I did try that; no dice:

ls -l ../gdb
-rwxr-sr-x  1 ppluzhnikov  procmod  4075816 Aug 10 20:21 ../gdb

../gdb -ex run ../a.out
...
Unable to find Mach task port for process-id 98439: (os/kern) failure (0x5).
 (please check gdb is setgid procmod)

I see. /usr/include/mach/kern_return.h says:

#define KERN_FAILURE                    5
                /* The function could not be performed.  A catch-all.
                 */

Not much help I am afraid :-(
