I tried compiling with -O0 ggdb3

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
*[root@localhost i386]#* debuginfo-install wpa_supplicant Package 1:wpa_supplicant-debuginfo-0.6.4-2.fc10.i386 already installed and latest version *[root@localhost i386]#* gdb -q wpa_supplicant (no debugging symbols found) (gdb)
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).
