I have an example where
cout << f(a) << f(b);
is calling f(b) before f(a), which I think is wrong. The operator<< is (in this case) a function call, so there should be a sequence point which guarantees evaluation order.
My apologies for submitting a bug on an old version.
Cygwin on Windows 2000
g++ gccseqtest.cc -o gccseqtest
I think this should be:
State-Changed-Why: no, there is no sequence point there. The code is
output (output (cout, f (a)), f (b));
where 'output' is the operator<< function. you'll see
that 'f (b)' can be called before or after
'output (cout, f (a))'
