Arithmetic exception in executor static chunker

[mcopik]

While trying to reproduce the issue #2281 I've found another problem, an integer division by zero for static chunk size when called from a parallel fill.
Source code: https://gist.github.com/mcopik/d34318766bb8dc8404255026c47a28c1
CMake script: https://gist.github.com/mcopik/7515e467cbb97b8a6ea983167f305a62
GDB backtrace with the exception:
https://gist.github.com/mcopik/b8e0e0f3b1137a4d46b7015fc8ed255c

Am I doing something wrong? Built and executed with current master.

How do I reproduce it? How did you run this code?

[mcopik]

Configure with cmake, build and execute on one thread (--hpx:threads=1) on my machine with 2 Xeon CPUs.
I've overriden CMAKE_PREFIX_PATH in CMakeLists to locate HPX's master build, provided in HPX_LOCATION.

Do you need something else?

The problem with your code is that you're trying to run HPX code without initializing the HPX runtime. I will make sure the corresponding functions in HPX will throw an exception in this case instead of silently ignoring this.
