Ahh, that explains it.

I tried rebasing your patch onto the current upstream/master, and I'm
hitting this assert:

  gdbsupport/array-view.h:190: internal-error: slice: Assertion `start + size <= m_size' failed.

I do compile GDB with `_GLIBCXX_DEBUG` defined in order to see that
assert.  I haven't looked into what might be going on here yet, but
thought I'd give you a heads up.

( Please let me know if you can't reproduce this issue, it is possible
  that I've managed to break something when merging/rebasing your
  patch. )

Thanks,
Andrew
