With the latest from cvs the core dump on "create table" is back
when compiled with -O2.

If I compile backend/catalog with -O2 then the table creation is
OK. So it looks like it may be indexing.c, even with Bruce's
recent fixes.

I'm still getting some regression test failures, the worst of which
is a core when creating a function.

Here's a bactrace from a "create function" immediately after an initdb
and using the template1 database.

Do you mean -O0 here?

I managed to get this running on a Solaris box.  -O2 was not included
by default (wonder why :)).  I got a core dump when running initdb
with -O2.  I recompiled indexing.c without -O2, and it is much better.
(I basically get the same results as under Linux.)  I get the same
core dumps that Keith is seeing with create function.

So, both my Sparc boxes are behaving the same.

I have looked over indexing.c and can still see nothing strange.  I do
remember that ProcedureSrcIndexScan/PROSRC cache call never worked in
the old code, so this call is now working, but that is the only
functional difference I remember.

The old code in this section was somewhat mangled.

Can I telnet into this machine?

My guess is that hTupDesc is badly formed, not having the proper
attributes for the relation.  Can you do a print of *hTupDesc, and
attrNums[0]?
