Note that, where `debug_backtrace()` accepts an argument, which lets you configure options for the backtrace, `getTrace()` has no such argument.
Whether the `getTrace` method captures arguments instead depends on the `zend.exception_ignore_args` INI setting, which must be set to `0` ahead of time, before an exception occurs. (notice the confusing double negation here - to *enable* capture of arguments, you must *disable* this INI flag.)
Unlike `debug_backtrace()`, the `getTrace` method does not appear to capture the `object` value.
