Possible Aetherling/CoreIR Memory Leak

[David-Durst]

My travis build fails because CoreIR's json to verilog compiler causes the VM to run out of memory on https://github.com/David-Durst/aetherling/blob/master/tests/haskell/convolution_32x32Im_2x2Win_1px_in_per_clk.py.

This doesn't seem like a large file.

Need to investigate why it's taking so much RAM.

This doesn't sound good... Definitely possible there are memory leaks with regards to the python api. Or possibly internal coreir memory leak bugs.

Could you do a test and just serialize it to json first, then in a separate process generate the verilog for the json?

coreir -i circuit.json -o circuit.v
