Here's what I do, in those cases:
M-x cd .../emacs/src
M-x gud-gdb RET gdb ... temacs RET
b maybe_call_debugger
r -batch -l loadup dump
[...crash...]
bt
the `r` line may need to be adjusted depending on whether the crash
happens for the generation of src/bootstrap-emacs or src/emacs: I just
copy&paste it from the failed build.
