Hi Daniel,
I've tried it on the latest gdb (6.3), however it is still not working.

This GDB was configured as "--host=sparc-sun-solaris2.9

(gdb) list *syn_cookie_ager
No source file for address 0x18e33d8.
(gdb)
Do you have any suggestions? As long as -ffunction-sections is removed
from my cflags everthing will be ok.
Yi

Sorry, but that version of GDB is so old that we can't help you with it.
You may want to try a more recent version of GDB.
