--- Comment #2 from Martin Uecker <uecker at eecs dot berkeley.edu> ---
It seems with the changes to lvalue conversion the code
volatile int x;
int i;
(x = 1, i = 2);
gets rewritten to
((x = 1, 1), i = 2)
and then build_compound_expr introduces the spurious warning.
There is a another possible related issue:
volatile int x;
(x, 0);
warns about
warning: variable ‘x’ set but not used
