Yosys Tool Crashing at "Executing ABC" with no errorcode

[krupatishbi]

Description

I keep encountering this error when trying to run any of my designs through OpenLane:

[ERROR]: during executing yosys script /openlane/scripts/yosys/synth.tcl
[ERROR]: Log: designs/snncore/runs/fullguide15/logs/synthesis/1-synthesis.log
[ERROR]: Last 10 lines:

52.5. Finished fast OPT passes.

53. Executing ABC pass (technology mapping using ABC).

53.1. Extracting gate netlist of module `\snncore' to `<abc-temp-dir>/input.blif'..
Extracted 782930 gates and 1134376 wires to a netlist network with 351444 inputs and 76648 outputs.

53.1.1. Executing ABC.
child killed: kill signal

[ERROR]: Creating issue reproducible...

There is no error code or anything in the synthesis error or warning logs, they are empty. But for some reason, ABC tool is not working for this.

Expected Behavior

The ABC tool shouldn't crash/exit for no reason.

ABC appears to have simply run out of memory. I ran this design on my computer and ABC used up to 6 GB of RAM.

This is sadly just the case for designs of this size. How much RAM do you have?
