[Buildroot] pthread broken in avr32 build

[Marco Cane]

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
