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.

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.
