In the following program...
==========
#define F
main()
{
 int a,b,c;
 if (c==0)            /* << extract */
  #ifdef F            /*    these */
   if(a==0) printf("a",a);      /*    five */
  #else                /*    lines */
   if(b==0)    printf("b",b);  /*       >> */
 #endif{}
 }
==========

...if you select lines 5 to 9 and invoke the Extract Function refactoring, CDT produces the following incorrect code:

==========
#define F
void extracted_function(int c, int a) {
    if (c == 0)
        /* << extract */
        if (a == 0)
            printf("a", a);
    /*    five */}

main()
{
 int a,b,c;
    extracted_function(c, a);
  #else                /*      lines */
   if(b==0)    printf("b",b);  /*       >> */
 #endif{}
 }
==========

The #else in main does not have any #if.
