https://issues.dlang.org/show_bug.cgi?id=24440 --- Comment #3 from Ivan Kazmenko <gassa@mail.ru> --- Originally got hit by it in my toy language project which I use to teach parallel computing. It maintains a three-dimensional array to store queues of messages between different simulated processes. For now, circumvented the issue by transforming it to a two-dimensional array of structs containing arrays. https://github.com/GassaFM/interpr/commit/b959bb7870 Still, multidimensional arrays are a pretty core language feature. Can I expect it would work again at some point?.. Ivan Kazmenko. -- |

The following code, given `1000 1000` on the first line and 1000 tokens in each of the subsequence 1000 lines from standard input, fails to run successfully and it is just "Segmentation fault" (DMD>=2.107.0, WSL2). ``` import std.conv, std.stdio, std.string; void main() { string[] tokens = readln.chomp.split; const M = tokens[0].to!int; const N = tokens[1].to!int; auto A = new string[][](M, N); foreach (x; 0 .. M) { tokens = readln.chomp.split; foreach (y; 0 .. N) { A[x][y] = tokens[y]; } } } ``` For further info, I found this at when solving a problem at https://yukicoder.me/ - my submission link: https://yukicoder.me/submissions/974786 where I see that when the input is smaller the segmentation fault does not happen (RE (Runtime Error) vs WA (Wrong Answer)). -- |

The expression `new long [][][](n, n)` creates memory, which is not scanned by the GC, but contains pointers. The GC will free the inner arrays and the program crashes, when they are accessed. -- |
