Issue ID: 18953
Summary: Win32: extern(C++) struct destructor not called
correctly through runtime
Product: D
Version: D2
Hardware: x86
OS: Windows
Status: NEW
Severity: normal
Priority: P1
Component: dmd
Assignee: nobody at puremagic.com
Reporter: r.sagitario at gmx.de
import core.stdc.stdio;
extern(C++)
struct S
{
int x;
~this() { printf("~S %x\n", x); }
}
void main()
{
S[] arr = new S[3];
arr[1].x = 1;
arr[2].x = 2;
arr.length = 1;
assumeSafeAppend(arr); // destroys arr[1] and arr[2]
printf("done\n"); // arr[0] destroyed by final GC later
}
The expected output is:
~S 2
~S 1
done
~S 0
Works for win64, but for win32 (both -m32 and -m32mscoff) I get
~S c0b831ff
~S c0b831ff
done
~S c0b831ff
