bug#33074: 26.1; images crash emacs

[Sam Halliday]

When I open any image file from Emacs, the process dies.

I ran inside gdb to find the cause of the problem and I guess it is a
bug inside the libmagick library that doesn't handle all the OpenCL
error cases (my graphics card is only partially supported).

Since this is affecting my use of GNU Emacs, I thought it best to use
the bug report tool but I am happy to consider this closed and raise as
a bug with libmagick. Preemptively created
