Mmmmh I don't follow you, this has nothing to do with the GC. It's rather a problem with the backend (i.e the translation to an IR andthe generation of byte code) Anyway someone already pushed a fix so next point release (~1 or 2 weeks) will not produce invalid code for the case you've found. Yes, ok I see. But anyway, thank for you help :D.

The struct address was somehow either not loaded correctly, or not passed correctly (didn't look into more detail which case). A regression should be filed for this, if not already.

Postblit segfault.
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 think the first is a pointer to function and the second is a function type itself but I'm not sure. yes this is correct. To declare a function type using the first form is also possible: alias TF1 = void(int); alias void TF2(int); static assert (is(TF1 == TF2)); Ok thanks you :D
