Description

Hi,

When compiling any program that includes Eigen with -fno-exceptions in Clang, compilation will fail with the following error:

In file included from Eigen/Core:252:
Eigen/src/Core/util/Memory.h:90:13: error:
array is too large (18446744073709551615 elements)
new int[size_t(-1)];
^~~~~~~~~~

This has been tested with both Apple's clang included in the iOS SDK 5.0, and a Linux x86_64 clang version 2.9 (tags/RELEASE_29/final).

Perhaps abort() or something similar in this situation would work?

Thanks,

• Aaron
