[dtrace-discuss] dtrace syscall:::return arg0 weidness on b56 ( x86)

[Paul van der Zwan]

At the moment I am attending course SA327 ( dtrace)
and I am doing the excercises on my macbook running  b56 on parallels.

In one excercise we have to list failing system calls using
a predicate: /arg0 == -1/ and this never matches on my system.
When I change the test into / arg0 == 429496729 / it matches.
On a Acer Ferrari running S10u3 the test for -1 works.

Any idea if this is a bug in b56 or what it might be otherwise ??
