AddOpenCLEvent in magick/cache.c causes Emacs to crash
Posted: 2018-10-17T02:09:12-07:00
When I try to open any image in GNU Emacs, the process crashes. I ran under gdb and discovered that it is a problem with libmagick. This is the line that causes the crash
A full backtrace and my clinfo is at the bottom of this message. I'm using the mesa opencl implementation for my graphics card which is only partially supported.
A workaround is to disable OpenCL
