FWIW, I am using a self-compiled gcc 4.5.2 / binutils 2.21.51.0.5
(AFAIR with apatch in as for one regression) with a Cortex-M3
(thumb-2 only) TI Stellaris processor without any problems.
So if there is any general problem regarding thumb, it either
does not affect thumb-2, or is platform specific, or is
a regression in 4.6.x.

Out of curiosity, why thumb-interwork? As long as everything
is compiled with -mthumb, according to gcc docs it is actually
contraproductive, isn't it? Maybe this is also the factor.

Looks more probable to me.
