With ET_2022_11, I’m finding the following error on at least two different machines when using the intel compilers:

error: more than one instance of overloaded function "isnan" matches the argument list:
            function "isnan(double)"
            function "std::isnan(double)"
            argument types are: (double)

and an equivalent error for the “isinf” function. The error points to lines 220 and 228 in the file cactustest/TestMath/src/math_cc.cc. If I comment lines 218-232 in this file (or prefix the the calls with "std::") it seems to compile fine.

One machine where this happens is Marenostrum 4, but bizarrely, whether the error shows up or not, depends on which modules (and in which order) are loaded.
