Please check if it works for your version too or otherwise report your GCC version. cross-compilation with GCC 9.2.1 on Linux still doesn't work

I was able to reproduce the problem by building in a NetBSD-9 chroot with a GCC host toolchain, but not with my -current LLVM host toolchain. I wonder if GCC miscompiles something.

I certainly do full release builds for all LLVM architectures and I don't get this. Yes, a clean build. I've done two again just now, on different physical machines. One has NetBSD, the other has Linux. I deleted the src and obj directories and started from scratch using github, with the following commands exactly as-is on both hosts from an empty folder: git clone https://github.com/NetBSD/src.git cd src ./build.sh -j 4 -U -O ../obj -V MKGCC=no -V MKLLVM=yes -V HAVE_LLVM=yes -m amd64 tools ./build.sh -j 4 -U -O ../obj -V MKGCC=no -V MKLLVM=yes -V HAVE_LLVM=yes -m amd64 kernel=GENERIC Both hosts fail the same way. My two tests from yesterday were on the same physical machine but with both NetBSD/Linux, using the same commands as above except that it was anoncvs instead of github, and both hosts failed the same way. Am I the only one seeing this? It's hard to blame the configuration when the failure is seen on several hardware and several OSes.
