Compiled with -inline:


import std.parallelism: taskPool;
void main() {
    int x = taskPool.reduce!q{a + b}([1, 2]);
}


DMD 2.058 head:

Assertion failure: '!vthis->csym' on line 678 in file 'glue.c'


The same code compiles and runs without errors without -inline.

Is this a regression? Did it ever work?

import std.parallelism;
void func() { }
void main()
{
    taskPool.put(task(&func));
}
-----------------
I can compile this code in dmd2.057, but cannot compile it in git head.
(dmd displays similar error message.)

This reduces to:

struct AbstractTask {
    ubyte taskStatus;
}

struct Task {
    AbstractTask base;
    alias base this;

    void opAssign(Task rhs){ }

    ~this()
    {
        if (taskStatus != 3) { }
    }
}
