 Replying to [comment:36 mascguy]:
 > Upstream PR opened for `darktable`, to disable signal handlers for
 `GraphicsMagick`. Thanks @parafin!

 Testing locally with this patch - combined with building via Xcode Clang -
 results in the following stacktrace:

 Definitely an improvement detail-wise, with the `GraphicsMagick` signal
 handlers disabled!

 Thoughts relative to the crash within `_platform_memmove`?
