I have tried this change, and now the first test case of this ER:

int[100] foo() {
    int[100] a;
    return a;
}
void main() {
    int[10_000] a, b;
    auto c = new int[10_000];
    a = 1;
    a = b;
    a = c;
    auto d = foo();
}

gives a ICE:

temp.d(8): Warning: explicit element-wise assignment (a)[] = 1 is better than a
= 1
temp.d(10): Warning: explicit element-wise assignment (a)[] = (c)[] is better
than a = c
Assertion failure: '0' on line 1193 in file 'glue.c'

Smaller test case:

void main() {
    int[1] a;
    a = 1;
}

> What version and compiler switch do you use? I cannot reproduce the ICE.

I am using the GIT head compiler, I have downloaded and compiled dmd few hours
ago, after this patch was merged.

I am on Windows 32 bit, and I have compiled the code with:

dmd -wi test.d
