State-Changed-Why:
    This is the known computed-goto cfg manipulation problem.
    We've got nearly complete connectivity between a very large
    number of blocks, and we eat all that ram and time futzing
    with the edges between them.
    
    As such, I'm closing this as a duplicate of 4313, which
    identifies the problem more clearly.

 Should I do something else than replying to all recipients of your mail?

 I finally managed to compile this file on an Alpha with 1GB with
 gcc-3.0 with
 
 gcc -mieee -c engine.i
 
 Top showed about 1550MB virtual memory consumption during most of the
 time.  Top showed that the CPU was mostly in system or idle mode, with
 only about 0.5% user time; took about 30 hours.  The compiler produced
 a file engine.o, so I assume the compilation went ok (unfortunately I
 was not smart enough to log the output and status).

 It needs to go to gcc-gnats@gcc.gnu.org to be filed with the PR.  GNATS
 status change messages used to include this address in the headers, but it
 seems they don't any more.  This is a bug in the bug tracking system
 configuration.

    Excess memory consumption is still a bug; changed from
