I've found that I can't even debug PIE executables with gdb, let alone core
files.
I encountered this problem when trying to debug gdb on itself. Downloading
the gdb source tree and building it with "dpkg-buildpackage -b" produced a
PIE executable that I couldn't set breakpoints on properly. The Debian
/usr/bin/gdb, though, is not PIE, which makes me wonder if someone
(Samuel?) is compiling our Debian packages without PIE, to avoid this
problem.
