Using a number of Fedora releases (and VMs), I tested
gdb.dwarf2/dw2-out-of-range-end-of-seq.exp with GDB builds with Gwen's
patch applied...

F35: pass
F36: pass
F37: pass
F38: fail
F38 (updated): fail
F38 (updated, no -O2 in GDB part of build): fail
F38 (circa May, 2023): fail
F38 (aarch64): pass
F39: pass
F40 (aka rawhide): pass

I used two different x86_64 F38 VMs, but they're related.  The "circa
May" F38 VM was cloned from the main one that I use for much of my
work, but I cloned it to look at a specific problem and
(intentionally) had not updated it since cloning.

I've also removed the debuginfod cache. Even with it deleted, I'm
still seeing the same failure on the x86_64 Fedora 38 VMs.

For all machines which show a pass for dw2-out-of-range-end-of-seq.exp,
I ran the new test using TESTS=gdb.reverse/recursion.exp to make sure
that I was really testing against a build with Gwen's patch applied. 
In each case, I saw 8 PASSes, so I was indeed testing what I had
thought I was.

I'll now do some actual debugging, comparing what happens with and
without Gwen's patch...
