Hello, I don't understand why this code segfault on
Linux/FreeBSD:
import std.stdio;
struct _Poc {
this(this) { writeln("_Poc.this(this)"); }
}
void main() {
_Poc[1] valueArray = [ _Poc() ];
writeln(valueArray);
}
I've just defined the postblit function in _Poc to see how much
it's invoked.
In my system, it's invoked 3 time after the segfault.
When the array is allocated on the heap, nothing happen.
So I guess it's because it's located on the stack but why?
regard.
I cannot help much, but I can say that problem is not about
postblit. I tried running the code on https://run.dlang.io/. It
works with LDC but not with DMD. Even though postblit is removed,
it crashes because there may be a bug with DMD's writeln or there
is something more that I missed too.
