I've heard from Ed Vogel in the compiler group and I include his explanation
below. The bottom line is that when we do a debug Perl build, we insert
/LIST/SHOW=ALL into the compile command, but /SHOW=ALL now implicitly
includes the new option /SHOW=CROSS_REFERENCE. This new option has a bug in
the current release of the compiler; just turn it off if you really need to
get util.c from the Perl sources compiled debug.
Many thanks to Ed for his quick, courteous, and knowledgeable replies to my queries.
