Description Tom Evans 2008-09-24 17:40:03 UTC 
py-xmlsec uses pkg-config to retrieve the CFLAGS required for compiling against libxmlsec1. It then marshalls them into an array for distutils.core.Extension to build and install the python module.

However, it has a bug where by py-xmlsec's setup.py reads in a CFLAG define present on 64bit configurations of xmlsec1, which is only specified as "-DXMLSEC_NO_SIZE_T" by xmlsec1's pkg-config. It passes this to distutils as the tuple '(XMLSEC_NO_SIZE_T)', which is interpreted by distutils as being a CFLAG undefine, and is passed into the build phase as "-UXMLSEC_NO_SIZE_T". This causes missized structures to be passed between the two, leading very quickly to a seg fault.

Fix: Replace security/py-xmlsec/files/patch-setup.py with attached patch (I hate patches of patches!)

Patch attached with submission follows:
How-To-Repeat: (on amd64)
cd /usr/ports/security/py-xmlsec
make clean all install
echo -e "import xmlsec\nprint xmlsec.keyDataRsaId().getName()" | python -
Segmentation fault: 11 (core dumped)
