failure 22:

Requirement failed: {cprojl.01} z projects to z, except that all complex infinities (even those with one infinite part and one NaN part) project to positive infinity on the real axis.

According to LSB, the cproj(z) family of functions shall compute a projection of z onto Riemann sphere: z projects to z except all complex infinities. The old implementation in glibc does a stereographic projection that contradicts the standard.
