Actually this is very bizarre.  A native compiled Emacs that has been
dumped has to go through there to startup so either:

1- we are debugging temacs and non emacs
2- emacs was compiled with native compilation
3- the breakpoint is not working as expected, maybe because it's an
optimized build.

I guess most likely we are looking at case 3 here.  Could you try in
this case building pdumper.c (or all Emacs) with -O0 -g3?

Thanks
