Hi Dlang community!
I've stumbled on an interesting issue with allocators. It seems
that we can't get disposed of arrays with const or immutable
data. Consider example below:
Link: https://run.dlang.io/is/frnQI8
------------------------------------
import std.stdio;
import std.range;
import std.algorithm;
import std.experimental.allocator;
import std.experimental.allocator.mallocator;
void main(string[] args) {
const(int)[] values = Mallocator.instance.makeArray!(const
int)([1, 2, 3, 4]);
writeln(values);
Mallocator.instance.dispose(values);
}
------------------------------------
We'd get following error:
/dlang/dmd/linux/bin64/../../src/phobos/std/experimental/allocator/package.d(2398):
Error: function
std.experimental.allocator.mallocator.Mallocator.deallocate(void[] b) shared is
not callable using argument types (const(int)[]) shared
/dlang/dmd/linux/bin64/../../src/phobos/std/experimental/allocator/package.d(2398):
cannot pass argument array of type const(int)[] to parameter void[] b
onlineapp.d(11): Error: template instance
`std.experimental.allocator.dispose!(shared(Mallocator),
const(int))` error instantiating
Is it expected to not be able to dispose out of immutable or
const data, or it is a bug that should be fixed?
