Did some trial and error. In _Image.cpp, the problematic lines apparently are the following two: scope* Magick_Blob_scope = new scope( class_< Magick::Blob >("Blob", init< >()) //--> .def(init< const void*, size_t >()) .def(init< const Magick::Blob& >()) .def("base64", (void (Magick::Blob::*)(const std::string) )&Magick::Blob::base64) .def("base64", (std::string (Magick::Blob::*)() )&Magick::Blob::base64) .def("update", &update_wrapper) //--> .def("updateNoCopy", &Magick::Blob::updateNoCopy, Magick_Blob_updateNoCopy_overloads_2_3()) .def("length", &Magick::Blob::length) ); But there are other problematic cases in e.g. _Image.cpp. Needs further investigation.
Created attachment 431176 [details, diff] Remove methods using void* arguments I've also suggested this approach upstream: https://github.com/ImageMagick/PythonMagick/pull/2

Thanks, the patch works for me as well.
Upstream 0.9.13 includes https://github.com/ImageMagick/PythonMagick/commit/659906f137907fb2f7569eac5cfe7ed2b28cd179 which should fix this. As far as I can tell it removes some of the methods I removed, and provides wrappers for some others to use std::string instead of void* and size_t.
Fixed in 0.9.14 in the tree.
