Crafty-23.1 malloc issue

[zullil]

For some reason I can't use hash=2048M with crafty-23.1, although I can with crafty-23.0. What am I missing here? I have an 8-core Mac Pro with 6 GB of memory.

Code: Select all

I have allocated large hash tables in Windows (larger than 2 GB) so I guess it is something POSIX specific.

It is likely a windows issue, related to the way I allocate aligned memory. If you can compile your own, I can send you an attempt at a fix that might work, but I am not sure. I can malloc 12gb on my cluster with no problems.

It works on Windows also. I think it is Mac specific.

Which version of Windows are you using Dan?

I am using Windows 7 Ultimate 64bit, and I can't use greater than 1024. When trying 2048, I get the following error:

This is definitely a 23.1 issue. Or just my compiles. I will have to look.

It works on my mac. I compiled with just "make darwin". Here's output:

crafty-23.1 $ ./crafty hash=2048M

But does it work if you try to make a 64-bit build? Try editing the Makefile to be

When I build from this I get

Oops, yes. I munge the code.

All the ints in the allocation routines need to be changed into size_t types.

[Aaron Becker]

But does it work if you try to make a 64-bit build?

Good catch. With a 64-bit build I get the same error. The problem is that the 'size' parameter of AlignedMalloc and AlignedRemalloc has type 'int'; it should be a 'size_t'. With that change it works correctly for me. Here's a patch of the changes I made:
