I ran into an oddity of pthread_create, see 
https://github.com/D-Programming-Language/druntime/pull/1340. It appears 
that if stack size is not explicitly set, the 32-bit version of 
pthread_create fails. That's happening at least on Ubuntu64 under VMWare 
hosted on Linux.

Unrelated: what's the deal with the build fail by CyberShadow/DAutoTest?

What is the stack size using pthread_getstacksize before the setting of it?

I would think with pthread_attr_init, it should be a reasonable default.

Yes it is a default, which is zero, so problem is somewhere else

pthread_getstacksize indicates 8,388,608 bytes. It doesn't seem 
excessive, but the 32-bit build does find that too big. If I try to set 
stack size to that value with pthread_setstacksize, indeed the thread 
fails. So it's not that you need to call pthread_setstacksize, you need 
to call it with a smaller value. -- Andrei

Does the failure always happen with any thread create? Or only after you 
have created X threads?

8MB doesn't seem like that much, but if you created 100 threads at 8MB a 
piece...

What about an equivalent C program? something doesn't seem right when 
the default value isn't working...
