NB crash boom

Why is this simple experiment crashing the vm? It seemed like such a small change from the getenv example that I was sure it would succeed. Mac 10.8.2 with lastest nbcog vm...

run: str
"self run: 'open http://www.google.com'."

        <primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode >
         ^ self nbCall: #( int system (String str) ) module: NativeBoost CLibrary

Thanks,
Sean

ahaha... system call..
yeah.. what could go wrong?
(was thinking me as well, when tried to demonstrate the use of this
function couple months ago :)

there is very complicated machinery behind this function (most in C)..
i have not much clues what happens, but i can imagine that it does
something which interrupts/blocks VM thread
(add there signals and stuff) until command finishes.. which VM can't handle..

i remember i did or checked something to make system() call working..
but i can't remember what exactly.

(so, i dunno, but your sample works fine on my machine with my VM ;)
.. and of course i am not giving it away, because its mine! :)

just lets wait till we will get fresh VMs, and we'll see :)

Yes I would put that even on high-priority for NB, as it is the most important
use-case that makes sense to me :D

Okay, thanks for checking. I can use OSProcess for now - I was just exploring.

That's not very friendly... I take back my "thank you" ;)

Let me know if you remember how you got it working...
