[PATCH] Set DEMANGLE_RECURSION_LIMIT to 1536

[Nick Clifton]

Hi Michael,

> I think this points toward the limit being _much_ too low.

Fair enough - several other people have said this as well.  So
I have proposed an alternative patch instead.  My current suggestion
is to raise the limit to 2048, which allows the libiberty patch to 
pass.  But do you have a feel for how much is a realistic limit ?

I do not think so.  Unless there are some long jumps in the demangling code ?
I did a quick scan and did not find any, but I could have missed something.
Plus of course I cannot guarantee that my patch is bug free, although looking
at it again I do not see where I missed a level decrement.  

I think that the demangling code just is really recursive...
