New Post: Memory doubled when using LUFactor

Thanks for the repro.

I can confirm:

• The process private memory is doubled while LUFactor is running, but freed right before it returns
• The additional memory does not seem to be managed memory.
• This only happens with Complex and Complex32, but not with double or float.
  

It may be caused by the marshaling of the Complex/Complex32 structure.
This may be tweakable by adjusting the structure layout and marshaling (maybe manual pinning and pointer/unsafe).

Update: would be great if we could avoid any copying at marshaling!
