pthread broken in avr32 build

hi,
this is my first post on this list.

I'm developing an embedded system based on the atngw100 board, powered by an Atmel AVR32 CPU but I found a big issue.
It seems that libpthread has some problems because every program using threads ends with a segmentation fault. I first discovered this bug while testing JamVM & GNU Classpath. All worked fine, but simple applications using Java threads behaved in unexpected manner, while they worked fine on my Ubuntu box
So I tried a simple C program like this
http://www.opengroup.org/onlinepubs/009695399/functions/pthread_join.html,
compiled by the toolchain and also by the installed gcc with the -lpthread option with the same result.

I also tried to compile uclibc with the new linux thread support but it's broken, due to a missing file (tls.h) for AVR32 architecture.

So my questions are:
1. has anyone experienced this bug and found any solution/workaround?
2. how can I retrieve, if exists, a snapshot of buildroot correctly supporting threads for AVR32? because I think something went wrong with some patches and I wonder if there is somewhere a working snapshot, older than recent ones

thanks in advance

Marco

There are some nasty problems in the AVR32 parts of gcc, I would bet these are the true cause of your problems. I'm hoping the folks at Atmel will give it some serious attention soon.

A friend of mine claims you have to use glibc to have threads properly working.
