Binary package hint: gcc-4.3

g++ ICEs when building qt4-x11 on powerpc. The complete build log is here:

  http://launchpadlibrarian.net/23399665/buildlog_ubuntu-jaunty-powerpc.qt4-x11_4.5.0-0ubuntu1_FAILEDTOBUILD.txt.gz

I've reduced the ICE to a reasonably minimal test case (although there were still two #includes that would have taken rather more effort to pare down), and preprocessed source is attached to this bug.

$ gcc -v
Using built-in specs.

Command line that triggers the ICE with minimal test case:
