I haven't been able to come up with one...  The most obvious areas to worry
about would be weird varargs/stdarg stuff, structure return addresses which
get passed around in extra registers and the like.

Hmmm, there may be an issue with the PA64 ABI with its somewhat weird 
convention
of having the caller pass a pointer to the arglist to the callee.  But I 
haven't
really thought it through yet.
