RE: [pushed] [PATCH V7 0/8] Intel(R) MPX register support

Hello Pedro and Yao,

I am followed the steps and description on the bug report but I am failing to reproduce it.

Yao,
I have tested a gdb/gdbserver built for I686 running full test suite and could not reproduce it.
Could you please provide more details about the reproducer?

Thanks and regards,
-Fred

BTW: Next patch we will squash i386/amd64/gdbserver. Should this three patches also be send for review as a single commit?
Sorry for that! :(

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!
