buggy uClibc config

I'm developing embedded Linux distro, and I saw that anything that requires pthread library dies with segfault in libpthread. Even simpliest 'Hello world' if it linked with pthread library. Any things like specifying -ldl at 1st place, using -pthread instead of -lpthread does nothing.
I use gcc-3.3.3 in toolchain, and uClibc-0.9.30.3. Sources are compiled for i686 CPU, target kernel - 2.6.32.10. In config I selected legacy pthread library.
uClibc config in attach.

Here is strace of segfault:
