Ditto, and also the one from OpenEmbedded.

Any particular reason you are not using 2.20? I'm using that right now
to test uClibc/NPTL, but if it has issues, I'll upgrade.

Ditto, I'm using 4.4.3.

I'm using 2.6.34.

I'm using nightly builds, latest tested was 20100703 (the week has been
intense enough I did not have time to pursue the tests any further, but
I'm now in WE, and have plenty of time ahead, or I should have...)

I did not try gdb yet, I will look into it once the core toolchain is OK.

Thank you for the report!
