It might be helpful to add -O0 as well, at least for modules you are 
interested in like so:

where-cc1-is-located> rm expr.o; make cc1 CFLAGS='-g -O0'

To start the debugger I use ddd which gives a minimum of GUI. Anyway, 
it's helpful to start gdb from the right directory like

where-cc1-is-located> ddd cc1
gdb> set args "command line args to cc1"
gdb> cd "dir where call took place resp. where .i is located"
gdb> ...

Also read the helpful extensions described in gcc/gdbinit.in This 
already sets breakpoints at internal_error, fancy_abort, exit and abort.
