GDB pie

It seems right now I can't get gdb to debug a program
compiled with gcc
as:

gcc -fpic -fpie -ggdb pie.c -o pie

Somewhere there were some patches floating around that
allowed gdb to
handle position independent executables; but I can't find
them* and
don't know if they're up to date.

Anyone have any ideas on this?  I know the patches are out
there
somewhere, it'd be nice if whoever wrote them worked into
getting them
into mainline, assuming they're still maintained.  Using
PIE binaries is
a security feature that can be found in RedHat and Gentoo;
it's
recommended to build the entire system PIE by the PaX
project as well.



*Google:  gdb "position independent executable"
patch; gdb "position
independent executable"; gdb position independent
executable; gdb pie
patch; gdb pie

Look for the two branches in the CVS repository whose name
contains
"pie".  Elena was working on this, but ran out
of time, and no longer
works on GDB.  That's all I know about it.

I don't??

John, have a look at the redhat gdb rpm, the patches are in
there.

Sorry, I thought you were entirely busy with
SystemTap/Frysk; I haven't
heard from you on this list in ages.  Good to see you, and I
apologize.
