iropt is the C compiler optimizer.

I had the same problem.  I bet you also used the default SPARCStation
configuration (UNIX, or SunOS, came pre-installed on my SPARC).

The file cfbbitblt.c is nasty to C compilers, and the problem here is
a lack of swap space, I believe (at least that's the general
impression from talking to Sun support).

What I did was compile that particular file by hand, using the
-O1 optimization level, rather than -O optimization.  This seemed
to work fine. I still used -O on the rest of the X sources.

Somehow it all worked, since I writing this using a SPARCStation-1
running MIT X11R3, and rlogin'ed to our machine that handles
Usenet news.

Hope this helps,

-Eric
