There isn't a flag to turn off array bounds checking - it would require compiling against different libraries.

I must have misremembered it from somewhere, perhaps confusing it with -fliberate-case-threshold mentioned a while ago (which probably belongs in the "experimental" category?) Turing off bounds checking could be fairly useful, I think, if there is a significant speedup to be gained. My impression is that the typical Ada programmer tests the program thoroughly with bounds checking, but compiles without for deployment. (Of course, we would rather *know* a priori that we're not going out of bounds, rather than just test for it, but it seems to work all right for them)

There are array operations that avoid bounds checking, however (eg. unsafeRead, unsafeWrite).

I suppose I can do it by wrapping array accesses in a class or otherwise, with a safe and an unsafe implementation, and switch when I'm satisfied things work. -kzm PS: is large file support in the vicinity yet? -- If I haven't seen further, it is by standing in the footprints of giants
