[clang-cl] clang-cl stuck when compiling such code with /EHa

[regomne]

struct S
{
    ~S() {}
};

class ClassA
{
public:
    int foo(int, int);
};

int ClassA::foo(int a, int b)
{
    if (a > 0)
    {
    }
    if (b & 0)
    {
    }
    S s;
    return 0;
}

Clang version: 18.1.8

Compile the above code in Windows with:

clang-cl /c /EHa a.cpp

may causes the clang-cl.exe stuck with a probability of 80%.

I can reproduce this with clang 18.1.8, but this doesn't happen with 19.1.7.
