Segmentation Fault for Exceptions in timestampNonceHandler

[ssigwart]

If you set up timestampNonceHandler and it throws an exception, it can cause a segmentation fault. To test, you can put something like this in the handler:

throw new RuntimeException();

On MacOS with PHP 8.0, I saw fatal errors like this:

Allowed memory size of 134217728 bytes exhausted (tried to allocate 5726624128 bytes) in

On Linux on PHP 8.0, it was causing segmentation faults.
