Commits: 41130f91 by Jacek Caban at 2025-05-22T11:53:54+02:00 ntdll: Mark IsBadStringPtr functions as noinline.
Without this, the compiler may inline them into dispatch_exception. When compiler exceptions are enabled, this causes a handler to be set up for dispatch_exception, which is unintended. A side effect of this is that EXCEPTION_NESTED_CALL may be cleared when a nested exception is dispatched.
This fixes test_nested_exception test on aarch64 when compiler exceptions are used.

This affects Clang in MSVC mode. By default, Clang treats __try/__except as regular exceptions, assuming that memory access doesn’t throw. As a result, it may incorrectly move code outside the exception handler or optimize away the handler entirely. MSVC always treats __try/__except as meaningful. Work around the issue by explicitly enabling -fasync-exceptions.
See https://github.com/llvm/llvm-project/issues/62606 more context.
