Hello Dan,

the GDB `frame' command supports syntax `frame FRAMEADDR' and
`frame FRAMEADDR PCADDR' where FRAMEADDR should be $sp in the caller.
See the doc, this is exactly its purpose.  It behaved a bit erratically now to
me on x86_64.

If/as this is not a common task one can use `eu-readelf -n corefile'
(eu-readelf is readelf from elfutils) and patch the registers using hexedit,
IIRC I was doing to before.


Regards,
Jan
