Hi Andreas,

Like Eli, I tried it, and it worked for me as well.

If we weren't already 4 weeks late, I might have given ourselves
an extra week to see if it got accepted, but we need to branch
soon and start stabilizing. Maybe the Global Maintainer reviewing
the changes will approve the changes for a backport, but it looks
a bit on the large side. Since it's before a .0, perhaps it'll be
considered safe enough for it.

I wish I could tell you that I would look into this, but my schedule
for the next few weeks is completely packed...

I reproduced the issue with 7.10, so not a regression. I'd guess
that this is a missing check_typedef somewhere, so might be fairly
simple to fix. I've added this item to the "maybe" list for 8.0
in the release's wiki page
(https://sourceware.org/gdb/wiki/GDB_8.0_Release).
