The assembler here reports the same:
$ /usr/libexec/gcc/darwin/x86_64/as -v
Apple Inc version cctools-795~45, GNU assembler version 1.38
^CInterrupted by signal 2
And after some checking I found that by disabling "--enable-libstdcxx-debug"
the compile process passed the current error, but failed later right after
comparing stage 2 and 3:
...

I guess this may be related to "--enable-fully-dynamic-string". But it looks
like a difference issue[1][2].

[2] http://trac.macports.org/ticket/31171
Anyway, "--enable-libstdcxx-debug" causing bootstrap failure should be a
problem.
