Thank you for checking.  You are right, this seems to be a version-specific
problem for Sourcery CodeBench.  I don't see an obvious bug in the assembly
code produce by these compilers:

@ GNU C++ (Ubuntu/Linaro 4.6.3-8ubuntu1) version 4.6.3 20120624 (prerelease)
(arm-linux-gnueabi)

@ GNU C++ (Ubuntu/Linaro 4.7.2-1ubuntu1) version 4.7.2 (arm-linux-gnueabi)
