Created attachment 878 [details] patch with fix This fixes failures in test rand on MIPS32R5. The failures are a result of undefined behavior in template<typename Scalar> struct random_default_impl<Scalar, false, true>. With certain values of arguments x and y there's a signed integer overflow in expression ScalarX(y)-ScalarX(x). This showed with the particular compiler version we're using for MIPS32R5. Also, the template wouldn't handle the whole range of Scalar when it's 64-bit (long long or __int64) on 32-bit CPUs. This should fix it as well.
Feedback/merge?
Thank you for the patch, looks good to me so I applied it in 3.3 and default branches: https://bitbucket.org/eigen/eigen/commits/1e5eebbd47f6/ https://bitbucket.org/eigen/eigen/commits/0333e646c842/
Was removal of is_integral<> intended in 3.3? Just checking.
I've been too fast, my bad
