postgresql-7.4RC1 - Memory fault(coredump) on HP-UX

Greetings,

PostgreSQL built with:

export CC=cc
./configure --without-readline --without-zlib

The build and install went OK.

{/opt/postgres/postgresql-7.4RC1}$ initdb -D /usr/local/pgsql/data

The files belonging to this database system will be owned by user
"postgres". This user must also own the server process.

The database cluster will be initialized with locale C.

Success. You can now start the database server using:
   /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data
or   /usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start

Can you show us the stack trace ?

Hm, getaddrinfo() is crashing?

Does HPUX 11 have more fields in "struct addrinfo" than are initialized in
lines 189-196 of src/backend/postmaster/pgstat.c, viz
hints.ai_flags = AI_PASSIVE;hints.ai_family = PF_UNSPEC;hints.ai_socktype = SOCK_DGRAM;hints.ai_protocol =
0;hints.ai_addrlen= 0;hints.ai_addr = NULL;hints.ai_canonname = NULL;hints.ai_next = NULL;
 

If so, perhaps adding "memset(&hints, 0, sizeof(hints));" right before
these lines would improve matters.

Otherwise I think this is probably an HPUX bug.  You might need to get a
more recent version of libc.
