Hi, it seems that in some occasions (i.e on malloc failure) pthread_create can return ENOMEM, which is not a valid POSIX error number. Attached there is a patch for libpthread to normalize ENOMEM to EAGAIN.
Thanks, -- Pino Toscano

Subject: [PATCH] pthread_create: turn ENOMEM to EAGAIN
ENOMEM can be returned if some malloc fail, but it is not a valid POSIX error number for pthread_create;
thus turn it to EAGAIN.
* pthread/pt-create.c (pthread_create): Turn ENOMEM to EAGAIN.
