Valgrind points at patadd(NULL, 0, nmeta, 0). Wonder why not to its
interior? But to all logic, problem should be inside patadd() because
nothing else near dereferences a pointer. So there might be two
problems. Debugger didn't report inaccessible memory when I did
step-over on the patadd(), maybe memory is accessible but invalid from
other reason recognized by Valgrind.
