[reportlab-users] Crash on debug builds of python 3.4.3

I'm working on embedding Python into my application as a scripting tool. I have therefore recompiled Python 3.4.3 using Visual Studio 2013, in both debug and release versions. I have also built the ReportLab 3.2.0 source release from pypi using the same environment.
When running the simplest of ReportLab samples (copy/paste from the user guide), I find that my Python interpreter crashes on shutdown (specifically, when calling Py_Finalize). The error appears to be a negative reference count on an object in the main Dict. The release version appears to work ok, though whether this is due to less error checking I don't know... Ignorance is perhaps bliss in this scenario. Note that this happens both inside my application (embedded interpreter) and the official python shell (python_d.exe crashed at the end of generating the user guide).
I guess my question is - is ReportLabs tested against debug builds of Python? Is the error genuine or false-positive (it's not too benign, the Python interpreter calls abort() for this fatal error...)?
