This bug was fixed in the package openoffice.org - 1:3.1.1-5ubuntu3

---------------
openoffice.org (1:3.1.1-5ubuntu3) lucid; urgency=low

  * Fix first build failure on ARM with -mthumb. LP: #506358.
  * Build with -O2 instead of -Os on ARM to work around GCC register
    spill errors.

This issue also effects building busybox. Will try the same using -O2 there.

succeeds with no error on
 g++-4.4.real (Ubuntu/Linaro 4.4.4-8ubuntu1) 4.4.5 20100728 (prerelease)

This might have been fixed by the Linaro compiler ...

Can't reproduce with gcc-linaro-4.4-2010.09. Confirmed that the http://gcc.gnu.org/ml/gcc-patches/2009-11/msg01545.html patch is present.

Based on that, marking as invalid.

gcc-4.4 is built on Linaro GCC 4.4-2010.09 or later, so this should be fixed here also.
