[32bit] python core dumps when using libdiscid package (cygdiscid-0.dll)

Hi
I would like to contribute and maintain the 'python-discid' package:
o https://python-discid.readthedocs.org (Homepage)
o https://github.com/JonnyJD/python-discid/archive/v1.1.0.tar.gz (Download location)
It uses the just uploaded/announced libdiscid-0.6.1-1 package. Packaging and
testing works fine under 64bit cygwin but under 32bit cygwin, python
core dumps already during the
/usr/bin/python setup.py config
stage of cygport. I'm not a debuging expert but here's what I get under
gdb after downloading the debug packages of python and libdiscid:
python2.7.exe.stackdump:
