Forthstrap issues

[Programmingkid]

I am having issues with making forthstrap work. The program is trying to access a memory address that doesn't belong to it. I think the problem is with the calculation of the variable latest. This line in bootstrap.c is where it is calculated: 	
*latest = target_ucell(pointer2cell(dict) + dicthead - sizeof(cell));

My question is is the variable latest suppose to hold the address of a memory location? I can't access that value immediately after it is set.

I believe it should be the LFA of the current word being defined in the 
Forth dictionary.

HTH,

Thanks. I figured out that the switch-arch script was the culprit. It was not identifying my system correctly.
