Is `kqueue()` nothrow? You probably need to decorate that
lambda with `nothrow`. (i.e. put a `nothrow` right after
`@trusted`.
Mike
`kqueue()` is not nothrow. From log: "Error: function
'core.sys.freebsd.sys.event.kqueue' is not nothrow"
This decoration does not solve the problem :(
But you're calling it from a `nothrow` function through a lambda
that is also not `nothrow`. Decorate your lambda as `nothrow`
and then, if you can't make `kqueue()` `nothrow`, put it in a
try-catch and figure out what to do if it does throw.
m_queue = () @trusted nothrow
{
try
{
return kqueue();
}
catch(Exception ex)
{
// what do you want to do about it?
}
} ();
