Re: [commit: ghc] master: Per-thread allocation counters and limits (b0534f7)

On second thoughts, alloc_limit needs to be signed.

* This is an integer, because we might update it in a place where

* it isn't convenient to raise the exception, so we want it to

* stay negative until we get around to checking it.

This only leaves 2^31 bytes = 2GB. I suppose the problem is more complex than I thought. On 4 May 2014 17:50, William Kenyon wrote:

According to google,

2^32 bytes = 4GB,

I think that is more memory than a 32 bit machine can handle anyway?

Maybe alloc_limit should be 32 bits on a 32 bit machine, and 64 bit on a 64 bit machine?

Does it make sense to have 64-bit alloc_limit on 32-bit box?

I think so. You allocate 2^32 bytes pretty quickly.
