--- Comment #5 from Kenji Hara <k.hara...@gmail.com> ---
It's intentionally introduced in:
https://github.com/D-Programming-Language/dmd/pull/5003

To fix wrong-code issue 14708.

Today, in Win64 and all Posix platforms, dmd uses exception handling table, and
it doesn't support using alloca in a function that contains try-finally
statement.
