                    functions
           Product: Wine
           Version: 1.7.22
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

PVS-Studio identifies Printing the result of identical functions Error,V681.
The language standard does not define an order in which the 'tlb_read_byte'
functions will be called during evaluation of arguments. tlb.c 650

...
printf("\\%2.2x \\%2.2x\n", tlb_read_byte(), tlb_read_byte());
...

According to the C++ language standard, the sequence of computing a function's
actual arguments is not defined. Which function will be called first depends on
the compiler, compilation parameters, etc.
