Comment (by parafin):

 GraphicsMagick is a red-herring in the backtrace - it installs its own
 SIGSEGV handler, so unless application does the same it shows up in any
 backtrace of an application linking to it. Which, I would say, borders on
 malicious behaviour.

 For source of the crash see frames 5-6, which is darktable's own code.
 This is probably a compiler bug. darktable ended official support for
 building on macOS 10.14 as of 4.0 release (Xcode version which is possible
 to install there is too old for the features we want, especially in
 rawspeed). It's possible though to build on macOS 10.15 with newer Xcode,
 but target 10.14 as deployment target (older ones are again not officially
 supported). This is how official macOS DMG package is created.

 As a debug suggestion I can propose disabling OpenMP to see if it avoids
 the crash. It of course will degrade performance significantly.
