>Description:
        Building pkgsrc/x11/qt4-libs fails with the following messages from the
        c++ compiler:

painting/qdrawhelper_mmx.cpp: In function 'void qt_blend_color_argb_mmx(int, 
const QSpan*, void*)':
painting/qdrawhelper_mmx.cpp:115:1: internal compiler error: in insert_save, at 
caller-save.c:1306
Please submit a full bug report,
with preprocessed source if appropriate.
See  for instructions.

        Since the compiler comes from the NetBSD base system, I am
        filing this as "Category: bin".

>How-To-Repeat:
        1. NetBSD 6.99.11 i386, built from sources checked out with
           cvs update -D"2012-09-15 12:00 UTC".

        2. pkgsrc source tree checked out from CVS with the same
           cvs update -D"2012-09-15 12:00 UTC".

        3. cd pkgsrc/x11/qt4-libs ; make

        I used a pkg_comp chroot, but I have seen the same problem
        without it.

        4. After a long time, it fails.  The last command, and the
        error messages, are:
