Description Bartek Siudeja 2019-10-25 05:28:15 UTC 
test on run.dlang.io
no compiler arguments
all dmd versions

code:
```
void main()
{
    auto data = cast(const char[5][]) "qwert";
}
```
output:
```
Up to      2.085.1: Success and no output
Since      2.086.1: Status -4 and no output
```
Nightly gives `output: Illegal instruction (core dumped)`.

Perhaps this is related to https://issues.dlang.org/show_bug.cgi?id=20318
Comment 2 Bartek Siudeja 2019-10-25 15:54:40 UTC 
Maybe a nicer way to reproduce, pointing at handling of strings:
```
    auto data = cast(const int[]) "qwer"; // not OK
    auto data2 = cast(const int[]) "qwer".dup; // OK
```
