This compiler error only occurs when I compile NEW_GC together with
UNION_TYPE=1, DEBUG_XEMACS=1, and OPTIMIZED_BUILD=1.  Please don't
compile NEW_GC together with UNION_TYPE, DEBUG_XEMACS, and
OPTIMIZED_BUILD.  Especially, please don't use NEW_GC together with
OPTIMIZED_BUILD, to keep backtraces clean.

No, it doesn't GC more, it error checks more.

APA> M-x show-memory-usage reports have been useless for quite a while.
APA> ISTR Stephen reported this before.

I missed Stephen's report, sorry.

APA> Why has the object memory usage report become basically useless?

Because I broke it a few months ago.  I'll commit a patch in a bit.
BTW, show-object-memory-usage-stats always worked.
