Reported by user in the forum post:

Python script:
~~~ python
import saxonc
s1 = 'This is a test.'
with saxonc.PySaxonProcessor(license=False) as proc:
print(proc.version)
xdm_string_value = proc.make_string_value(s1)
print(xdm_string_value)
xpath_processor = proc.new_xpath_processor()
xpath_processor.set_parameter('s1', xdm_string_value)
result = xpath_processor.evaluate('$s1')
print(result)
print(result.get_atomic_value().string_value)
~~~
I ran the same sample python script under linux with gdb command:

There seems to be a memory handling issue. Investigating now.
