[posixtest-discuss] Openposix: pthread create, testcase 1-6

[Patrick K. <pk...@su...>]

Hey all,
I have a question on testcase pthread_create/1-1.c :
there is shared variable "int *ctrl = (int *) arg;" in function
"hp_func" which should be protected through pthread_mutex or similar, right?
As I understand this shared variable should always be protected?
So is there a reason why there are no pthread synchronisation calls?

As you can see in the suggested temporary patch below, is it possible to
add volatile-statement to the shared variables?

I'm asking, because sometimes this testcase fails on s390x.
