Bug#1067956: rocalution: FTBFS on armhf (test failure with memory allocation)

[Cordell Bloor <cgmb@slerp.xyz>]

Control: severity 1067956 important

The rocalution package has never successfully built for armhf, so I 
don't think this qualifies as release-critical.

It's great to see that the rocalution package gets all the way into the 
tests before failing, though. The upstream project only officially 
supports amd64, so that's better than I was expecting. The tests should 
probably skip anything requiring more than ~2 GB of memory when running 
on 32-bit architectures. Patches are welcome.

Sincerely,
Cory Bloor
