Why do you classify the testcase to be invalid code? Neither OpenMP nor C
forbid the use of a label there. Is this an undocumented restriction of the
&&-extension?

Also, clang and icc accept the code despite the use of the && GNU extension.
For both compilers the resulting binaries produce reasonable output.
