I created pr with reproducing bug, its producing segfault (only on windows)
https://github.com/kelbon/kelcoro/pull/48
```cpp
dd::task<int> foo1(int i) try {
abc c;
for (;;) {
if (i == 42)
co_return 0;
co_await std::suspend_always{};
try {
bar(c);
break;
} catch (std::exception& e) {
// here `e` already dead,
std::cout << '"' << e.what() << '"';
}
}
throw "";
} catch (...) {
co_return 0;
}
```
Notes:
memory where exception allocated is dead when catch block starts.
Its important that `break` in the try block, even if it is switch `break`, not break for `for` loop
Access violation reading location 0xFFFFFFFFFFFFFFFF.
