Created attachment 885696 [details] emerge --info libcxx-18 added stack system header to its imported header leading to this unusual behaviour with clang accepting executables in include paths to happen. https://github.com/llvm/llvm-project/commit/82d21814e6556480a71c83a2f8da350d0c8cadf6 $ cat test.cxx #include <iostream> $ ls stack # executable test.cxx $ clang++ -I. -c -o test.o test.cxx # failure $ clang++ -c -o test.o test.cxx # success $ g++ -I. -c -o test.o test.cxx # success Id argue this is a bug with clang rather than elfutils.

I can also reproduce this using gcc-full.conf on package.env I gonna include my logs and env file
Created attachment 886633 [details] efutils build log and gcc-full.conf env file
Created attachment 892277 [details] build log Adding build log for dev-libs/elfutils-0.191 using llvm profile and # clang --version = clang version 18.1.4+libcxx

I had assumed it was been broken for longer.
