In this noncompliant code example, pst is not properly released when processItem process_item throws an exception, causing a resource leak:
| Code Block |
|---|
|
#include <new>
struct SomeType {
void processItemprocess_item() noexcept(false);
};
void f() {
SomeType *pst = new (std::nothrow) SomeType();
if (!pst) {
// Handle error
return;
}
try {
pst->processItem>process_item();
} catch (...) {
// Handle error
throw;
}
delete pst;
}

try {
