No, it's not.  Your idea of how a C compiler is supposed is broken,
instead.  Actually, any compiler *not* outputting two identical
strings, in this particular situation, would have to be called broken.

No. What this code does, according the definition of C, is:

1)a)	evaluate expression 'var1'  
1)b)	evaluate expression 'func1' 
2)      call printf

There is no specification whatsoever about the order in which 1a) and
1b) happen, in the C standard, only that both must have been finished,
before printf() is called.  They may even be done simultaneously, as
far as the standard is concerned.
