Hi Fred,

Unfortunately, this caused PR16193 - gdbserver aborts.

Could you take a look, please?

<https://sourceware.org/bugzilla/show_bug.cgi?id=16193>

((
BTW, while bisecting this, I found that the MPX series as committed 1dbcd68 fails in early initialization with:

../../src/gdb/amd64-linux-nat.c:1180: internal-error: _initialize_amd64_linux_nat: Assertion `ARRAY_SIZE (amd64_linux_gregset32_reg_offset) == amd64_native_gregset32_num_regs' failed.
A problem internal to GDB has been detected, further debugging may prove unreliable.
Quit this debugging session? (y or n) [answered Y; input not from terminal]

nothing we can do now, but just a friendly note to point out that it's a good idea to try to avoid this, to make bisects easier.
))

Thanks!
