I'm seeing a segfault when building wxPython with SIP 4.19.11.

Running command: sip
/usr/bin/sip -w -o -g -I /home/talbert/Downloads/wxPython-4.0.1/src -I 
/home/talbert/Downloads/wxPython-4.0.1/sip/gen -c /tmp/tmpdH4lfu -b 
sip/cpp/_core.sbf -X pycode_core:wx/core.py sip/gen/_core.sip
Segmentation fault (core dumped)

4.19.8 worked ok.
