Thread-topic: inTaskWithOptions failing if capacity less than alignment on Leopard

Having a strange issue on Leopard with inTaskWithOptions function.

I have a driver which works on Tiger where a memory buffer gets allocated successfully when the capacity is 128 bytes and alignment is 4096.

However same driver code is not working on Leopard, the call to inTaskWithOptions fails.

Any idea why this could be happening?

Is it a requirement on Leopard to specify capacity bigger than the alignment in the call to inTaskWithOptions?

Thanks,

Lalit.
