Thanks for the kind offer, but I'm not sure how you would get the OS to use a 
replacement stack.  Typically, the top of stack pointer is kept in a location 
which would vary between OS versions.  Also, I believe that the stack used by 
USERDEF code is private to the process, i.e. there is a separate one for each 
DA plus the running app (plus one for the screen manager??).

There are other reasons to increase this stack size in EmuTOS, and if that 
bypasses the CFLIB problem, so much the better.  But, as Vincent noted, 
changing this in EmuTOS would not help users of early TOS versions (and I 
suspect there are lots more of those than users of EmuTOS).  So if you're 
interested in fixing this, I think it would be better to spend your time on 
fixing CFLIB.
