Reduced testcase:
===
struct A
{
~A();
};
void foo();
void bar(int i)
{
A a;
if (i)
foo();
else
for (;;)
foo();
}

: Search converges between 2004-11-19-014001-trunk (#644) and
2004-11-19-161001-trunk (#645).
It looks like this was introduced by one of your patches on 2004-11-19, Dorit.
Btw, here's an even shorter testcase:
struct A
{
~A();
};
void foo();
void bar()
{
A a;
foo();
for (;;)
foo();
}
