            Bug ID: 50383
           Summary: CUDA compilation fails if <complex> is included
           Product: clang
           Version: 11.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: CUDA
          Assignee: unassignedclangbugs at nondot.org
          Reporter: dontbugme at mailinator.com
                CC: llvm-bugs at lists.llvm.org

The file: "/usr/include/c++/11.1.0/complex" contains function named "polar",
which does the following test:

__glibcxx_assert( __rho >= 0 );

which breaks CUDA compilation. Commenting the above line solves the issue. The
error is as follows:

error: __host__ __device__ function '__failed_assertion' cannot overload
__host__ function '__failed_assertion'
      __glibcxx_assert( __rho >= 0 );
