The sigaction handlers for catching exceptions have been fixed quite a  
while ago already to only collect the necessary information from the  
signal context, and to then return from the signal handler to the  
start of the RTL function that handles run time errors, passing this  
info as arguments (we can pass at least 3 items on every platform by  
modifying the parameter register contents in the signal context; we  
also change the instruction pointer in the context so that it returns  
to the RTL's runerror handler rather than to wherever the signal was
