[Numpy-discussion] 64bit issue?

Hello I'm running into some strange error on a 64bit machine,
I tracked it down to this line returning a NULL pointer, any idea why is 
this?
I tried both numpy1.1.1 and what in trunk, numpy.test() passes for both

Ok here's the uname of the machine and the offending line:

Linux quartic.txcorp.com 2.6.20-1.2320.fc5 #1 SMP Tue Jun 12 18:50:49 
EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

  array = (PyArrayObject *)PyArray_SimpleNew(d, dims, self->type);

where d is 3 and dims: 120,46,72
self->type is 11

it seems to pass with d=1, but i'm not 100% positive.

Any idea on why it could be failing?

Thanks,

C.

PS: just in case here are numpy.test results:
 >>> import numpy
 >>> numpy.test()
