Hello,

I am trying to locate a piece of code in gdb 6.3
which does srack unwinding in AIX (5.3). When
unwinding the stack in my C code, I noticed a lot of
dummy frames whose pc points to the data segment
and/or outside th text segment(s). Can someone tell me
how gdb identifies such dummy frames and wherein the
code base it is? rs6000-tdep.c contains some algo for
frameless function detection etc.., but that isn't all
to it.

thanks

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