The ACT tools are only available internally to Sun.

No problem. Finding arguments on amd64 is a pain. We have been working with the Sun Studio and GCC folks to create an option to always push arguments to the stack a la 32-bit x86, as well as the associated MDB changes to grab this information. This will be available soon. We're also working on a programmatic method of disassembling the text and deriving the original arguments. In the meantime, you're stuck using the method described in my blog, above. While slow and annoying, it does work. - Eric -- Eric Schrock, Solaris Kernel Development http://blogs.sun.com/eschrock
