After the fix I posted earlier is applied so that the new Andrew
"malloc" detects that it's being built for a SPARC and aligns blocks on
8-byte boundaries, nothing seems to work; applications drop core shortly
after they're started up.  It happens while they're doing static loads;
part of the data structure pointed to by ClassList is overwritten by
some data from an "index" file (possibly "/usr/andrew/dlib/atk/index"). 
The overwritten part was OK before the explosion (I'd stuck in code to
call "class_DumpAllClassInfo to "stdout" at the end of
"class_EnterInfo").

If I put the old version of "imalloc.h" back, so that it doesn't notice
it's being built for a SPARC, this doesn't happen (although, of course,
"malloc"ed blocks don't get put on 8-byte boundaries, so "malloc"ed
blocks,including commons from ".do" files, that contain "double"s cause
bus errors).

I haven't investigated any further.
