I think this points toward the limit being _much_ too low.  With template 
meta programming you easily get these mangled names, it's not even a 
particularly long one.  But I'm wondering a bit, without tracing the 
demangler, just looking at the symbol name and demangled result I don't 
readily see where the depth of recursion really is more than 1024, are 
there perhaps some recursion_level-- statements skipped?


Ciao,
Michael.
