Ganache crashes when running truffle debug

I am running ganache 1.3

My test code appears to run successfully, and I am able to see the transaction appear in ganache. However, when I run truffle debug txId I get the following error:

This error occurs when debugging any transaction and causes ganache to crash.

Currently running macOS Mojave 10.14

I get this issue often. I use brownie + ganache-cli, when tx reverts (gas usage: 2m) brwonie sends debug_traceTransaction, and ganache crashes after this

file ganache-core.node.cli.js switch (o) { case "POST": var d; try { d = JSON.parse(f); } catch (e) { return (s["Content-Type"] = "text/plain"), void c(n, 400, s, "400 Bad Request"); } if (d instanceof Array) for (var u = 0; u < d.length; u++) { var b = d[u]; t.log(b.method); } else t.log(d.method); if ("eth_subscribe" === d.method || "eth_unsubscribe" === d.method) { (s["Content-Type"] = "application/json"), c(n, 400, s, a(d.id, -32e3, "notifications not supported")); break; } e.send(d, function (e, t) { (s["Content-Type"] = "application/json"), c(n, 200, s, JSON.stringify(t)); //<---------------- CRASHED HERE }); break; case "OPTIONS": c(n, 204, s); break; default: (s["Content-Type"] = "text/plain"), c(n, 400, s, "400 Bad Request"); } });

I believe this happens when the data ganache attempts to send back to the client is too large for the current node process to JSON.stringify; it just runs out of available memory. One way to solve this is to start the ganache server process with more memory (--max-old-space-size=8192), another is for ganache to implement https://github.com/trufflesuite/ganache-core/issues/381 and from truffle debug to use it.
