Is your working tree clean? I tested in both 10.2.x and 11.2.x and even latest 12.x with yesterday pull. It won't show anything when compiling with driver, i.e. g++, but if you run "cc1plus", it will crash. For example, ${GCC_INSTALL}/libexec/gcc/x86_64-unknown-linux-gnu/11.2.0/cc1plus -std=c++20 ./lambda-uneval11.C Thank you
