That's just SIGKILL (128+9). Which is normal for the OOM killer.

Well, sparse does keep a _lot_ of stuff in memory, and the "do many files 
at once" will basically keep every single one (with full types, full 
linearization etc) in memory at the same time.

It's probably fairly easy to fix: I should just make sparse release all 
the linearizations and symbols when they go out of file scope.

The "do many files at once" thing really was just a quick hack, so the 
lack of memory release is not that susprising.

I'll see what I can do.
