Ok, now I really want to know why it crashes. I've narrowed it down to
an example below. It seems there is a problem with RefCounted being
used as value in a map.

I think it crashes because of using associative array. Assignment to an
absent aa member causes memory allocation without proper object
construction, and immediately after compiler issues call to opAssign for
not-constructed object - that is why "this" pointer is "bogus" on
entering function.
import std.stdio;
struct S
{
int i = 42;
struct SS
{
int ii = 41;
this(this) { writeln("SS postblit"); }
void opAssign(SS rhs) { writeln("SS opAssign"); }
}
SS ss;
this(this) { writeln("S postblit"); }
void opAssign(S rhs)
{
writeln("S opAssign");
}
~this()
{
writefln("i=%d, ii=%d", i, ss.ii);
}
}
S[int] map ;
// S[2] map;
// S[] map = [S(), S()];
void main()
{
map[1] = S();
}
AA version on windows 2.060 prints
SS postblit
S opAssign
i=42, ii=41
i=4269990, ii=4269984 //garbage
Switching to dynamic or static array fixes the program.
Same problem under Linux. Somebody, please file this bug! Thank you! :)
