Once again, let me bring up the numerical noise issue on ARM. The problem is that while we pretty much narrowed it down to a particular function computing the log of the gamma-function, lgammal, in elibc, an implementation of libc used on Ubuntu 11.10 (on ARM, at least), the chances that the upstream fixes it seem to be rarher slim. Fixing it myself does not look trivial – this C code is not at all pretty, uses a lot of hardwired largish constants, etc etc (and we cannot just patch a system library easily anyway, so it needs to get into the upstream, etc etc...)
I can produce doctest patches that will to the appropriate rounding, but this potentially would make the corresponding doctests less reliable (we talking about things like 120.0 vs 199.99999997 for gamma(float(6)), something like this). As far as I know, doctests cannot be OS-dependent. Any way out of this Catch-22?
