Well, since you're trying to do something cutting edge and unsupported
it seems like you will have to debug the problem using gdb and, if you
really want this to work, make a change to autoload.cc to fix the
problem.  Look at a call frame for normal program and find where
the return address is stored.

Either that or wait for us to move to a newer version of gcc.
