Debug version of firefox

[Michael Zhilin]

Hi,

pstack shows firefox methods for example:

----------------- thread 100583 (running) -----------------

   0x102d568 0x7fffffffe360 main (102d10b, 0, 0, 0, 15, 0) + 1e8 in firefox
   0x102d10b 0x7fffffffe3b0 _start (1084000, 8, 0, 0, 15, 0) + 10b in
firefox

Information about methods is stored in dwarf2 structures of files. I
suppose it should be enough for debugging by GDB.
Is it not enough?

Thanks!
