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... Kevin
