hello,

 Im doing a stack analysis on AIX/IBM p615 and I find
that there are quite a few intermediate stack frames
that contain a pc pointing to the data segment (using
AIX terminology).
 Im aware that this is a netbsd forum -but the
convention adopted is OS independent (kind of) and hw
specific.
gdb has some provision to unwind the stack. Can
someone explain how one goes about detecting dummy
frames and why they exist?

thanks

In theory, there is no difference between theory and practice. In practice, there is.
