I don't know if there's a better place to store inadvertently-gained knowledge, but I ran into this today and figured it might benefit someone else in the future.
My julia build was failing during the creation of sys0.o: ... deprecated.jl basedocs.jl precompile.jl Killed make[1]: *** [/home/seth/dev/julia/usr/lib/julia/sys0.o] Error 137 make: *** [release] Error 2 Turns out that 256 MB of RAM isn't enough for this operation. Deleting the 0-byte sys0.o and rerunning make with more memory (+1 for dynamic VPS) solved the problem.
