Thanks for help a lot.
Bug seems resolved and we are cooking new toolchain (by re-applying fixes to 2010.10 \
or will get it from Linaro's git, doesn't matter). I will retest it soon.
With best wishes,
Leonid

Hi Leonid,
You do indeed have a compiler bug here!
We now have a fix for it, and the Linaro GCC sources should be updated
in the next few days.
If you don't want to wait for that, you can find the patch here:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45805
Apologies for the inconvenience.
Andrew
