Debugging firefox 1.0.4 on Linux: SIGKILL trouble

Hi there!
I am trying to run firefox under gdb but windows is showing for a few 
seconds and crushed then.

Here is gdb processing:
-------------------------------------------------------------------------
gdb /usr/local/lib/firefox-1.0.4/firefox-bin -fullname -nx -quiet
(gdb) set edit off
(gdb) set confirm off
(no debugging symbols found)...
Using host libthread_db library "/lib/libthread_db.so.1".
(gdb)
(gdb)
(gdb) set print static-members on
(gdb) tty /dev/pts/2
(gdb) set width 0
(gdb) set height 0
(gdb) set stop-on 1
(gdb) handle SIG32 pass nostop noprint
(gdb) handle SIG43 pass nostop noprint
(gdb) set print asm-demangle on
(gdb) cd /usr/local/lib/firefox-1.0.4/
(gdb) run
(no debugging symbols found)...

Here is firefox configuring info:
-------------------------------------------------------------------------
export MOZILLA_OFFICIAL="1" &&
export BUILD_OFFICIAL="1" &&
export MOZ_PHOENIX="1" &&
./configure \
             --with-system-zlib \
             --with-system-png \
             --enable-application=browser \
