  I was unable to reproduce that issue,
and I suspect that this is just an error on me side:
I probably just copied parts of two different gdb sessions.

  When trying to reproduce it, I always got internal (negative) numbers
that were different (more negative, meaning created later)
for the "longjmp" breakpoints as compared to their "longjmp master"
equivalent.

  Sorry to have generated that confusion,
