State-Changed-Why:
The bug is fixed on the 3.2 branch but still present on
mainline. It's a regression from 3.0.x where the code
compiled fine - thus "high priority".
BTW, the problem can be demonstrated with the following reduced testcase:
-------------------------snip here-----------------------
struct A
{
long long x, y;
void bar () const
{
A a;
a.y = ~y;
if ((a.x = -y)) ++a.y;
}
void foo (int) const;
};
void A::foo (int i) const
{
if (i) bar();
if (i) bar();
}
-------------------------snip here-----------------------
The bug seems to be target specific since it does not show up
on mips-sgi-irix6.5.
