Does GDB's core file say something interesting about where did GDB
crash?

Anyway, since no one responded, let me rephrase the (implicit)
question in Francesco's report: Is GDB supposed to handle invalid
memory accesses gracefully?  That is, if the user asks GDB to access
the inferior's memory via an invalid pointer, does GDB protect itself
against SIGSEGV and other related calamities?
