OpenMP example for PULP not working

[fconti]

What you see is quite strange. I just tried with a fresh download of:

- PULP RTL, latest master: https://github.com/pulp-platform/pulp
- PULP SDK, latest tag: https://github.com/pulp-platform/pulp-sd...2019.03.02
- PULP RISC-V GCC, version 1.0.10: https://github.com/pulp-platform/pulp-riscv-gcc (I downloaded this one prebuilt)

I tried to run pulp-rt-examples/cluster/fork, and it works fine:

Code:

Can you share some details on your setup, in particular version (or commit hash from git log) of PULP RTL you are running on? Can you try the same test I mentioned?
