Conversion error for ulong -> uint (as a size_t) on 32-bit linux

[PiotrekDlang]

What is current policy for dealing with ulong -> size_t conversion?

dmd -main -unittest allocator.d

Maybe the code wasn't tested on a 32-bit machine?
Andrei doesn't maintain this repo and instead develops in one of his Phobos branches.
AFAIK, he currently prepares std.allocator for inclusion in std.experimental.

Thanks Martin for stopping by.

The fix may be trivial however I wanted to ask for official approach to the conversion issues from size_t real types.
I plan to include the module in

Yeah, that confused me as I initially indeed checked his Phobos branch. And there is no issue tracker enabled.

Just FYI. I played a bit with the code and after changing the problematic ulongs to size_t I had to comment out a few asserts and a couple of crashing tests. Maybe I will prepare a PR to the proper repo tomorrow or a day after. You can safely ignore this thread for some time.
