I'm on Windows 10, but without the anniversary update (and I have no options on update plan)

In fact if I run the code given here Re^6: Win32::API and keyboard hook, I can crash perl after some/many keystrokes.

The error messages is emit at the call of the perl sub:

Attempt to change a readonly variable

or

Odd number of elements in hash assignment

I pass a sub reference to be called by the c hook function, and it's the code that receive the parameters from the c function that crash:

sub {
        my ($cup, $code, $alt, $ext) = @_;
        ....
}
