`crypto.generateKeyPair` results in an abort

[zyscoder]

• Version: v16.0.0-pre
• Platform: Linux 5.8.0-38-generic The binary and long term compatibility with node #43~20.04.1-Ubuntu SMP Tue Jan 12 16:39:47 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
• Subsystem: crypto.generateKeyPair

What steps will reproduce the bug?

Setup a node instance,

» node

and run the following javascript code.

crypto = require('crypto');crypto.generateKeyPair('dsa',{modulusLength:0,divisorLength: 2147485780},(err,publicKey,privateKey)=>{});

Then the node instance occurs an abort.

How often does it reproduce? Is there a required condition?

This abort can always be triggered following the steps above.

What is the expected behavior?

If any error occurs, an exception or other similar error-reporting stuff should be thrown. There is no reason to abort the whole node process.

What do you see instead?
