require("https").createServer({key, cert}, (_, res) => {
res.write("ok");
res.end();
}).listen(4000);Save and run the script and in a second terminal create some load:
npx autocannon -d 5 -c 300 -p 10 https://localhost:4000Server should consistently crash within a few seconds.
How often does it reproduce? Is there a required condition?
Every time
What is the expected behavior?
To not crash
What do you see instead?
It will crash with seemingly random crash signatures. Some examples:
node(74236,0x10a8e7dc0) malloc: Incorrect checksum for freed object 0x106920440: probably modified after being freed.
Corrupt value: 0x7b0a0d30310a0d0a
node(74236,0x10a8e7dc0) malloc: *** set a breakpoint in malloc_error_break to debug
[1] 74236 abort node try.js
node(74448,0x108606dc0) malloc: *** error for object 0x1068189fb: pointer being freed was not allocated
node(74448,0x108606dc0) malloc: *** set a breakpoint in malloc_error_break to debug
[1] 74448 abort node try.js
[1] 74410 illegal hardware instruction node try.js
[1] 74874 segmentation fault node try.js
Additional information
I don't see the crashes when using http, only when using https or http2 modules. Also I could not reproduce on Linux or Windows. Node was installed using Homebrew.
Crash does not happen with res.end("ok"), only with res.write("ok"); res.end().
