#36490: cctools: lipo assertion failure and crash
--------------------------+------------------------
 Reporter:  ryandesign@…  |      Owner:  jeremyhu@…
     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.1.2
 Keywords:                |       Port:  cctools
--------------------------+------------------------
 lipo is crashing again with an assertion failure on certain input files
 (files less than 4 bytes long). This is like #36081, except that
 rebuilding cctools has not helped.

 {{{
