#359 Crash on loading "very" large mesh

[Ronan Thibaudau]

I'm using meshlab to do some first path optimization of meshes before passing those meshes into other tools, it's been working fine so far with high poly meshes (2GB .obj files) but pushing it higher i'm getting generic crashes "the runtime has terminated . . ."
This happens during file loading on a 45GB file once meshlab's memory usage is at around 107GB, it's not a memory issue as this is on windows server 2012 64bit & the server has 256GB of ram (with some software i used on it happily using 220GB without crashing).
I'm sure this is an odd request (i assume most users of mesh lab are 4/8/12/maybe 16 or 32 gb of ram users) but it's actually pretty important to me.
I'd be very happy to provide meshes to repro this as well as remote desktop access to the server where I'm doing this if it can help at all.
Thanks for the great tool!
