gcc-linaro 2012.01 has the same issue, although the code it generated was a
little different.
gcc-4.7 snapshot 20120128 appears to have the same issue.
(I couldn't build the whole 4.7 compiler due to configure issues with
GCC_NO_EXECUTABLES in the final phase, and hence couldn't link an application,
but the cut-down gcc executables from the earlier build phases could compile to
object files just not link. The disassembly of the .o files generated by those
early-phase gccs indicate the same issue)
