pthread fails if low mem

[Matthieu CASTET <matthieu.castet@xxxxxxxxx>]

Hi,

We are using codesourcery 2006Q3 arm toolchain, our target has about 
10MB free memory and is running 2.6.20 linux kernel.

If we eat more than 2 or 3 MB of mem (less than 7 MB free mem left) then 
pthread_create fails with -EOMEN.
It successes if we don't eat memory before thread creation (9-10 MB free).


If we use a toolchain based on Uclibc (+ linux pthread), there no such 
problem : we can eat 10 MB and we can still create thread.

Have you got an idea why codesourcery nptl show such behaviour ?


Thanks,
