| Do you have any idea of why this happens ?? Bug in gcc ?

When I use gcc 2.7.2 to compile builtins.cc on a Linux system, gcc
grows to about 16MB, but that's it.

What else are you running?  How much free memory is really available
on your system?

Of Octave?  I'm not sure, but I have been making test releases of
2.0.10 lately.  They are available on ftp.che.wisc.edu in the
directory /pub/octave/test-releases.
