            Bug ID: 236839
           Summary: gcc8 failed to compile on sparc64 platform (FreeBSD
                    12.0 STABLE)
           Product: Ports & Packages
           Version: Latest
          Hardware: sparc64
                OS: Any
            Status: New
          Severity: Affects Some People

GCC8 fails to compile on SPARC64.  The port fails with the compile error
messages (truncated for brevity) included below.  

Errors from the build (i.e. cd /usr/ports/lang/gcc8 && make)

---> CUT HERE <---
Comparing stages 2 and 3
warning: gcc/cc1obj-checksum.o differs

===> Compilation failed unexpectedly.
---> END CUT <---

Summary:

It would *appear* as though that GCC is comparing the output from the stage2
and stage3 compiles, but stage 3 is being built with debug info being attached. 

This conclusion is based on examination of some of the files in question from
the error above.
