The following (invalid) code segfaults DMD (2.053).
enum qux = foo();
int[] bar = [[]*[[]<>[]]*[]]; // can be anything that is not an int[]
int foo(){
foreach(t;bar){}
return 0;
}
void main(){}
It does not matter what the initializer of bar is at long as it is not an int[].
The segmentation fault still occurs if bar is set to immutable.
Compilation output:
Error: static variable bar cannot be read at compile time
Segmentation fault
