gcc47: Segmentation fault in build/genattrtab

[dougmencken@…]

I'm trying to build GCC 4.7 with MacPorts. That's what I've got:

$ sudo port mdmg gcc47
Password:
--->  Computing dependencies for gcc47
--->  Building gcc47
Error: Target org.macports.build returned: shell command failed (see log for details)
Log for gcc47 is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc47/gcc47/main.log
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

It was a second unsuccessful attempt after I upgraded Xcode tools to the latest available ones (v3.1.4).

gcc47/main.log is attached. Parts of log which looks related to this error:

It is happening at stage2 of GCC bootstrap:

$ cat gcc47/work/build/stage_current 
stage2

Is this still a problem with 4.7.1?
