Problem getting 7.0 up and running

============================================================================

POSTGRESQL BUG REPORT TEMPLATE
============================================================================

Your name : Keith Chayer
Your email address : kchayer(at)bbcnet(dot)edu

System Configuration
---------------------
Architecture (example: Intel Pentium) : Intel 486 DX2-80, AMD
K6/2-300, 64 megs RAM on each(forgive me, the AMD was all we had)

Operating System (example: Linux 2.0.26 ELF) : Linux 2.2.14 and
2.2.15 (ELF of course), glibc 2.1.2

PostgreSQL version (example: PostgreSQL-6.5.1): PostgreSQL-7.0

Compiler used (example: gcc 2.8.0) : gcc 2.95.2

Please enter a FULL description of your problem:
------------------------------------------------
I listed two machines above--I have this problem on both of them.
I configured Postgresql with a bare configure command (no added
switches). It configured, compiled, and installed just fine. However,
upon running 'initdb', I get the following results:

**********************
postgres(at)bohr$ initdb -D /usr/local/pgsql/data
This database system will be initialized with username "postgres".
This user will own all the data files and must also own the server
process.

Creating database system directory /usr/local/pgsql/data
Creating database system directory /usr/local/pgsql/data/base
Creating database XLOG directory /usr/local/pgsql/data/pg_xlog
Creating template database in /usr/local/pgsql/data/base/template1

Adding template1 database to pg_database
/usr/local/pgsql/bin/initdb: line 481: 4643 Segmentation fault
"$PGPATH"/p
ostgres $BACKENDARGS template1 <"$TEMPFILE"

initdb failed.
Removing /usr/local/pgsql/data.
Removing temp file /tmp/initdb.4613.
**********************

This happens every time I run initdb. I have not been able to
successfully build postgres and get it running on either of these
systems. The systems used to be RedHat 5.1, but I've downloaded and
compiled about everything imaginable from source so there's little trace
of that left. They are both very similar in configuration--one used to
be the other one until I got a second machine and copied the 486 to the
AMD. I try to keep everything upgraded on them together, with only
system-specific differences on each.

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
I guess I don't know--from searching around the Postgres documentation,
I couldn't hardly find any references to segfaults. Even the mailing
list archives didn't seem to mention them much (the ones I could make
the search work on). Once I install, the initdb produces the above
results.

If you know how this problem might be fixed, list the solution below:

I wish I knew!
