array "history" on PPC OS X

Hi,
I get the following error when I try to run gnuchess 5.07 on OS X  
10.4.6:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x9672f5e8

I tried to rename the array "history" and it works now, but i'm not  
sure whether this was my mistake or something that should be fixed.
