/*
* On Solaris 2.6, when the function being jumped to is an external symbol of
* a shared library, the jump actually points to an ELF indirect jump:
* jmp *PTR
* where PTR initially contains the address of some resolving routine which
* will replace the PTR contents with the actual code address of the function
* and then jump to the function.
* Unfortunately, this resolving routine clobbers all three registers:
* %eax, %edx, %ecx. Must pass the additional data via the stack.
* A simple "pushl $<data>" is not sufficient: it causes trouble if the called
* function is compiled with -fomit-frame-pointer.
