Works with dmd-2.059. Does not work with the current github snapshot and with
dmd-2.060.
Strangely, if the "this" function is not defined for the Foo struct. The code
works fine -- no segfault. Alternatively if I store the value returned by
alomicLoad in a local variable before returning it from the function foo, the
code still runs fine.
// minimal code that gives segfault
import core.atomic;
struct Foo {
private ulong _s = 0;
public this (ulong s) { // no segfault if this function is commented out
this._s = s;
}
}
auto foo () {
shared static Foo bar;
// shared frop = atomicLoad(bar);
// return frop; // no segfault
return atomicLoad(bar); // segfaults here
}
void main() {
foo();
}
