Post any defects you find in the released or beta versions of the ImageMagick software here. Include the ImageMagick version, OS, and any command-line required to reproduce the problem. Got a patch for a bug? Post it here.
I just installed ImageMagick on my MacBook pro (Sierra), version 7.0.5, in order to use with LaTeX (converting PDF output to PNG). This command line crashes with "Abort trap: 6"
How did you install -- from IM binary, from IM source, from MacPorts or Homebrew? If you installed from IM binary, then that binary is only for El Capitan and not Sierra.
