[MINC-development] me, I'm stumped

[Jason Lerch]

Hello again,

there is no documentation that I could find about IRIX and large files,
so I tried John's solution. Turns out you also have to add the NDEBUG
symbol. Nevertheless, it still crashes at the same place with the same
error, so no luck here. 

I guess it is time to start searching for bugs in the minc library
source code ...
