Description Ali Ak 2018-03-08 20:37:33 UTC 
The following seg faults:

template A(T) {
  static foreach(I; 0 .. 1) { }
  alias A = T;
}

void main() {
  A!int a;
}

$ dmd -o- -X main.d

Comment out the static foreach and it won't segfault anymore.

Tried with dmd v2.079.0-beta.1 and dmd v2.078.3 locally, and on run.dlang.io you get:

Since      2.076.1: Segfault and no output

It seems to be fixed:

$ dmd -o- -X main.d
Error: module `main` is in file 'main.d' which cannot be read
