darcs patch: Support an interrupt flag, and primitive... (and 4 more)

If you are working from the main repository, there is a patch which  
breaks new bootstraps (just unpull it to get it removed from your  
local repository), titled:

"Added comments to Root methods and replaced the use of withSeen: in  
primitive slot recursion methods with &seen:."

You do not need to bootstrap in any case to get the work-around,  
since that just modifies boot.c; running the default make target to  
build the VM should be sufficient.

However, I have not seen this error you are describing, so I cannot  
address that specifically.

Basically, don't bother until you have a good reason to (for now). :)
