cc1plus: internal compiler error: Segmentation fault: 11

When I tried rebuilding the audio/pulseaudio port on -CURRENT, it
would fail with:

I was able to isolate the problem by patching the ports configure
script to remove -Wmissing-include-dirs from DESIRED_FLAGS.  This port
then built successfully.

As a test, I added -Wmissing-include-dirs to CFLAGS (/etc/make.conf)
and proceeded to build x11/kdelibs3, this port failed in its configure
script with the same segmentation error.

I then created test.cpp:

#include <stdlib.h>

int
main ()
{
  ;
  return 0;
}


and when I compiled this test program with an invalid include
directory, it failed:

 cc -I/usr/nolocal/include -I/usr/include -Wmissing-include-dirs test.cpp
cc1plus: internal compiler error: Segmentation fault: 11

Shouldn't it be reporting that the directory /usr/nolocal/include doesn't exist?

If I specify the correct paths, the test program still fails with:

cc -I/usr/local/include -I/usr/include -Wmissing-include-dirs test.cpp
/var/tmp//ccFe3FKQ.o(.eh_frame+0x12): undefined reference to
`__gxx_personality_v0'

Is anyone able to reproduce these problems?
