[zyscoder]

Bug Report

• Version: v0.33.0-dev
• Platform: Linux 5.8.0-38-generic Buffer 对象增加copy和concat方法  #43~20.04.1-Ubuntu SMP Tue Jan 12 16:39:47 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
• Subsystem: crypto.randomBytes

What steps will reproduce the bug?

Setup a fibjs instance,

» fibjs

and run the following javascript code.

crypto=require('crypto'); crypto.randomBytes(-125)

Then the fibjs instance occurs an abort.

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

This problem 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 crash the whole fibjs process.

What do you see instead?
