Thanks! It fixed the problem! it seems qt runs fine with eglibc and thumb.
To build qt with -O2 i changed my local.conf adding:

FULL_OPTIMIZATION_pn-qt4-x11-free = "-fexpensive-optimizations
-fomit-frame-pointer -frename-registers -O2"

To fix that upstream I do not know where it should be placed as it
should affect all distro using gcc 4.4.x?

Best regards

it would be helpful if you could narrow down the case. There is a
possiblity of gcc bug here but a testcase would be required.

in qt4-x11-free recipe you could use EXTRA_OEMAKE variable to add O2 to CFLAGS probably.
