2014-06-19 Thread Travis Scrimshaw
I just build 6.3.beta4 and when building the doc, I noticed large memory usage spikes when compiling the "master document"s. I ended up eating up all of my RAM (4 GB) plus swap space (2 GB) when running it in parallel (4 cores/threads) and it was trying to build 3-4 different master documents.

[sage-devel] Advisory: Severe bug in flint's primality testing code

2014-06-19 Thread Bill Hart
Hi all, Dana Jacobsen recently advised us that certain composites were being passed as prime by flint's primality testing functions n_is_prime and n_is_probabprime. This in turn affects n_is_factor which did not provide a factorisation of these numbers. This bug has been fixed in flint-2.4.4, and
