[mnet-devel] Help with mnet/fec/mmap/w32

[rob kinninmont]

So I was tapping away today at code that pokes at mnet.

I believe I got it to do a 'put' of a file, and since then the Node has 
exploded every time I've tried to put a file.

I spent a while delving into the code to figure out exactly where it 
explodes (specifically it segfaults, sorry gets an 'access violation', 
when the C code in fecmodule tries to turn around and call 'mmap.mmap' 
i.e. "mmapobj = PyObject_Call(mmapfunc, mmap_args, mmap_kwargs);" in 
the FileToMmap function)

So currently I can run Mnet fine as long as I never try to 'put' a 
file, when the Node crashes and exits. Doh!

The really curious thing is that when I tried tickling RizzoEncoder and 
ZNFFEncoder manually from python it worked fine.  It only explodes when 
it's called within Mnet.

Any ideas about why that might be the case?  Or what can be done about 
it?  Or at least how to figure out more informative information...?

dudes,
rob
