cppcheck 2.10 internal error for user defined literals

[penguish]

Running cppcheck 2.10 on the following code produces
"Internal Error. MathLib::toLongNumber: input was not completely consumed: 2_Tesla [cppcheckError]"

#include <iostream>

constexpr double operator"" _Tesla ( unsigned long long b ){
    return b*10000.;
}

int main(){
  const double f=2_Tesla;
  std::cout<<f<<std::endl;
  return 0;
}

Environment is centos7; we habitually use gcc 11.2 compiler with c++ 17 std.
