44973640: Spotlight Importer fails on Mojave with SIP enabled. Code signature error "not valid for use in process using Library Validation: mapping process is a platform binary, but mapped file is not"

Description

Summary:
Spotlight Importer fails on Mojave with SIP enabled. Code signature error "not valid for use in process using Library Validation: mapping process is a platform binary, but mapped file is not"

This affects the production version of Evernote (version 7.5)

The importer works as expected if SIP is disabled

Steps to Reproduce:

• Ensure that SIP is enabled
• Launch Evernote
• Create a new account or sign in with an existing one
• Create a few notes with unique or distinct titles
• Test the Spotlight Importer by running:
  mdimport -g <path/to/importer> -d2 <path/to/external/record>

Expected Results:
mdimport should output at least a kMDItemTitle attribute for the given record

Actual Results:
No title attribute is output. An error similar to the following is observed in the console:

<path/to/importer>: code signature in (<path/to/importer>) not valid for use in process using Library Validation: mapping process is a platform binary, but mapped file is not

Version/Build:
macOS 10.14 (18A391)

[cbfiddle]

I have encountered the same problem with my application.

I have also observed this failure running mdimport on a Spotlight importer that appears to work (QuarkExpress). It may be that mdimport is broken, but normal Spotlight does not use it?
