Description

The following code:

env CC=clang CXX=clang++ ./configure --disable-all --enable-intl --enable-debug --enable-zend-test --enable-address-sanitizer --enable-undefined-sanitizer
make

But I expected this output instead:

A successful build.

PHP Version

This is a long-standing and known issue. The project should be linked with clang++ FWIU for it to succeed. I pinged @petk about it but don't know myself what the right resolution is.

See this #18535

The main issue in short is that PHP in Autotools uses C compiler for linking when building C++ objects but it should use C++ compiler.
