--- Comment #4 from David Binderman <dcb314 at hotmail dot com> --- Sorry, I should have mentioned this: foundBugs $ ../results.20260310.ubsan/bin/gcc -v Using built-in specs. COLLECT_GCC=../results.20260310.ubsan/bin/gcc COLLECT_LTO_WRAPPER=/home/dcb42/gcc/results.20260310.ubsan/libexec/gcc/x86_64-pc-linux-gnu/16.0.1/lto-wrapper Target: x86_64-pc-linux-gnu Configured with: ../trunk/configure --prefix=/home/dcb42/gcc/results.20260310.ubsan --disable-bootstrap --disable-doc --disable-multilib --with-build-config=bootstrap-ubsan --with-pkgversion=02926c0abb71e211 --enable-checking=yes --enable-languages=c,c++,fortran Thread model: posix Supported LTO compression algorithms: zlib zstd gcc version 16.0.1 20260310 (experimental) (02926c0abb71e211) foundBugs $ -fchecking=yes probably makes a difference. In the compiler crash, I see: during RTL pass: outof_cfglayout bug1188.c:48:1: internal compiler error: verify_flow_info failed
