This fails on recent dmd versions with -debug:
/////////////////////////////////////////////////////////////////////////
module app;

struct Stuff {
    size_t capacity;
    size_t[1] items;

    void grow() {
        const oldCapacity = capacity;
        items.ptr[0 .. oldCapacity] = items.ptr[0 .. oldCapacity];
        items.ptr[oldCapacity .. 1] = 0; // Segmentation fault (code -11)
    }
}

void main() {
    Stuff stuff;
    stuff.grow();
}

run.dlang.io's "All dmd compilers (2.060 - latest)" mode claims the problem
started in 2.094.1:

Up to      2.093.1: Success and no output
Since      2.094.1: Failure with output: Error: program killed by signal 11
