Severity : critical

Summary: Semaphores and gcc 2.8.1 on IRIX 6.2 do not work

System Configuration
--------------------
Operating System : IRIX 6.2

PostgreSQL version : 6.4.2

Compiler used : gcc 2.8.1

Hardware:
---------
Indy Webforce, 96M RAM, plenty 'o disk
IRIX lust 6.2 03131015 IP22

Versions of other tools:
------------------------
gmake, flex

--------------------------------------------------------------------------

Problem Description:
--------------------
It took me a long time to isolate the real problem, but
you can't use gcc to compile textbook semaphore code on
IRIX. I guess it is a library format mismatch.

Regardless, any calls to semctl result in a BAD ADDRESS error.

--------------------------------------------------------------------------

Test Case:
----------
Compile w/ gcc. Install
Run postmaster -i
Run psql.
As soon as postmaster tries to grab some semaphores, you get
the error. It is reported by postmaster, and hangs.

--------------------------------------------------------------------------

Solution:
---------
Compile w/ SGI's cc.
Make sure you start completely clean (remove entire dist),
make clean doesn't seem to hack it. My first cc install cored.
My second build (fresh) was fine.
