Comment (by angerman):

 > Here's a github gist for a shell script that generates a giant stack
 project (with 150 generated dependencies) that triggers the panic:
 ​https://gist.github.com/asivitz/f4b983b2374a6155ac4faaf9b61aca59 I'm not
 sure the best way to do the same thing without using stack, but if you
 have an idea I can do that.

 This will generate 150 direct dependencies. As such any dylib that will
 reference those, will have to reference 150 libraries, in the load
 commands section. I don't think we can do much about this case. If this
 was 150 transitive dependencies spread over a few levels. we might.

 For 150 direct, we could potentially only work around this by using the
 splitting approach from nix. For 150 transitive dependencies, I still
 believe recursive linking could solve this. (See
 https://github.com/angerman/dylib-linking)
