Segfault with >1 thread with -O3

[murfel]

I get a segfault on line test.c:700 data[i].effective = effective; when 2 or more threads specified. When I compile with -O2 or lower, the segfault is gone.

I tried running as ./bin/spray and as ./run_throughput.sh as well. I only tested this on SprayList.

P.S. I definitely do not expect jkopinsky to look into this, just leaving this as a known issue for anyone else who plays with this code.

I think this could possible be fixed by this: #3
