After running

(gdb) source test.py

did you get this error message ?

Traceback (most recent call last):
  File "i:\share\gdb/python\gdb\__init__.py", line 129, in _execute_file
    compiled = compile(file.read(), filepath, 'exec')
  File "test.py", line 1
    import sys
              ^
SyntaxError: invalid syntax

If so, it looks that the python function compile() has an issue with \r\n.

which was fixed in python 3.2
https://docs.python.org/3/library/functions.html#compile

As workaround you can change line 129 of
i:\share\gdb/python\gdb\__init__.py" from

-            compiled = compile(file.read(), filepath, 'exec')

to

+            compiled = compile(file.read().replace('\r\n','\n'),
filepath, 'exec')

I have also applied this fix to the obs builds that should be available
soon at https://kmymoney.org/snapshots.php#gdb-snapshot. For 32bit
builds, look for the term "29.1" in the download URL and "16.1" for
64bit builds.
