Yes, that would be good. On the bug reproducing note, I'm getting lost as I'm not familiar with ARM ecosystem (this is pretty much my first serious encounter). I could not find Ubuntu 24.04 for 32bit "armhf", only for 64bit "arm64". IIUC the issue occurs on "armv8l" which is 32bit ARM code running on 64bit ARM CPU, right? Running on armhf QEMU, compiling GDB with Debian-provided toolchain does not exhibit the issue for me. I could not find Linaro-provided toolchain for armhf-linux-gnueabi systems targeting armhf-linux-gnueabi, only cross-compilation toolchains.
