           Summary: function call stack disorder.
           Product: gcc
           Version: 2.95.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: objc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: i18rabbit@hotmail.com
                CC: gcc-bugs@gcc.gnu.org

The following function call fails:

foo(fgetc(FPOINTER), fgetc(FPOINTER), i);

---

int foo(int x, int y, int i) {
    ...
}

receives the 2nd fgetc() char as "x",
and the 1st fgetc() char as "y".

The following works correctly:

x=fgetc(FPOINTER); y=fgetc(FPOINTER)
foo(x, y, i);

What platform are you using i686 on linux or otherwise?
Also can you provide with full source that causes the problem, this sounds like a missing 
prototype of the functions.

The test case is invalid as ANSI/ISO C say the order of excucation between squence 
points are undefined, so gcc exucutes the right one first and then the left one so this 
prefectly valid thing for gcc to do, correct your code as you suggested fixes it.
