Nested exceptions

[David Chisnall]

Hi,

I'm getting this warning from some of my code:

ERROR: Removing exception handler that is not on top of the stack.  
(You probably called return in an NS_DURING block.)

I am not calling return in an NS_DURING block, but I am raising an  
exception in one of these blocks (the parser throws an exception to  
the tokeniser, which then throws a more informative one including  
source locations).  Do I need to do something to remove the current  
handler from the stack before I do this?
