https://issues.dlang.org/show_bug.cgi?id=14768 --- Comment #1 from Kenji Hara <k.hara.pg@gmail.com> --- (In reply to deadalnix from comment #0) > enum Items = 174762; > uint[32][Items]* items; In front-end code, the total size of static array type is limited by 0x1000000, and uint.sizeof * 32 * 174762 = 22369536 = 0x1555500 Therefore the overflow error is not a bug. In fact, the overflow error is raised from 2.060, in windows platform. I'm not sure why it had not been checked in Linux platform, but an overflow check logic refactoring had actually introduced in: https://github.com/D-Programming-Language/dmd/pull/3949 So I guess there was an accepts-invalid bug, and it's fortunately fixed. -- |

First, this limitation is not in the spec so it is not expected that it is there (especially since it used to work). So it is expected to work (the limit is 16Mb, we are in 2015 we should be able to handle that much memory). And even if we choose that this does not require fixing, the spec needs to be updated, and the error message as well. index 174762 overflow for static array does not mean anything. There is no array access, so how can an overflow occur ? -- |

Good catch. From: http://dlang.org/arrays "The total size of a static array cannot exceed 16Mb. A dynamic array should be used instead for such large arrays." > > index 174762 overflow for static array does not mean anything.
