Looks like this is the segfault in #2128. Build the README example the way the install section says (link STDEXEC::stdexec, or just -I the include dir) and nothing compiles in the parallel scheduler's backend, so on GCC 15/ Linux (all I tried) it links fine and then crashes on the first line of main.

The godbolt link passes -DSTDEXEC_PARALLEL_SCHEDULER_HEADER_ONLY=1, which is why it works there. hello_world.cpp is the same code and gets the define or the compiled lib from examples/CMakeLists.txt, so the new line under the example names those same two options.
