Strictly speaking, one needs some additional information, fixing the 
initial parser stack size at a suitable value. I am not sure why 
alloca isn't usable in embedded systems; perhaps it is not available. 
And, if the parser stack is fixed, how is overflow handled. And if it 
is set too a high value, isn't that a poor use of the scarce memory?
