[Clang] Clang hangs when compiling valid code involving std::thread and lambda with --std=c++23 #151451
Description
Clang trunk hangs when compiling following program under C++23 mode. The same code compiles successfully and quickly with --std=c++20.
Program
#include <thread>
int main() {
std::thread memory_thread([]() {
const int alloc_size = 1024 * 1024;
while (true) {
char *buffer = new char[alloc_size];
if (buffer == nullptr)
break;
delete[] buffer;
}
});
return 0;
