Clang code model: __LINE__ macro has the same value in every line

It seems like the clang code model uses the same value for the _LINE_ macro in every line of a source file (in my case 85). This leads to errors, e.g. if _LINE_ is sued to create a local variable in a macro like in the following constructed example:

#define FOO2(l) int x ## l = 0;
 #define FOO(l) FOO2(l)
int main(){
     FOO(_LINE_);
     FOO(_LINE_);
 }

A clang warning is printed in the editor "redefinition of 'x85'" for the second FOO(_LINE_)-line.
