I was playing around and caused the compiler to hit an assert.

The code:

import std.conv;
void main(string[] args) {
    ubyte[6] array;
    if (array[0..5] == 6*[to!ubyte(0)]) {
    }
}


The assert:

$  dmd ./test.d
dmd: e2ir.c:1962: elem* toElem(Expression*,
IRState*)::ToElemVisitor::toElemBin(BinExp*, int): Assertion `!((tb1->ty ==
Tarray || tb1->ty == Tsarray || tb2->ty == Tarray || tb2->ty == Tsarray) &&
tb2->ty != Tvoid && op != OPeq && op != OPandand && op != OPoror)' failed.
[1]    497 abort (core dumped)  dmd ./test.d
