Python 3.6.3 on Windows 7 64 bit.

I keep getting intermittent crashes of Python.exe with my project. The error is below and as best I can see seems to be indicating the issue with the LZMA module.

All I'm doing is using it to compress web-pages (typically XML ones). Problem is, I can't replicate it. When I try and run the process again, the page that previously crashed it now works. I've had this happen three times so far (out of about 150,000 pages downloaded and compressed).

My use of LZMA is quite simply:

from lzma import compress
compress(page_content, preset=5)

The pages it has crashed on so far (but which work fine now):
http://www.geoportal.rlp.de/mapbender/php/wms.php?inspire=1&layer_id=35833&request=GetCapabilities&service=WMS&version=1.3.0

I took a mini dump (attached) and full dump using Process Explorer. The full dump is 100MB compressed (1GB uncompressed).
