I need to pass arguments to the called function, anyway gcc or
ppc-linux-gcc does not give any warnings for the same.

This is what is creating problem. both myfunc=test and myfunc=&test compiles
and executes as expected using gcc.
however ppc-linux-gcc gives error with myfunc=&test ->
<error>
invalid lvalue in unary '&'
</error>
while with myfunc=test compiles, but gives segmentation fault on running.
