I wanted to write it short but it was not clear I see.
So just one of the choices:
Either
(a) gdb /usr/bin/wpa_supplicant
and use debuginfo-install wpa_supplicant
(the line stepping will work but it will be "imperfect")
or (but not both)
(b) Patch wpa_supplicant.spec with `-O0 -ggdb3' but do not install it at all,
use just the version from the build tree. I use `rpmbuild -bc' for such
cases. Do some:
gdb /root/rpmbuild/BUILD/wpa_supplicant-0.6.4/wpa_supplicant (unchecked)
You can also do (if you need the binary present at the standard system
location such as in /usr/bin):
(c) rpm -U wpa_supplicant-0.6.4*.rpm
but do not use debuginfo-install but instead install also its
corresponding locally built debuginfo:
rpm -U wpa_supplicant-debuginfo-0.6.4*.rpm

If you do
rpm -qi wpa_supplicant wpa_supplicant-debuginfo
you should find out their builds do not match. I am more curious gdb should
have printed also:
warning: the debug information found in "/usr/lib/debug//usr/sbin/wpa_supplicant.debug" does not match "/usr/sbin/wpa_supplicant" (CRC mismatch).

Jan
