linking with `cc` failed when using `reqwest`

[rossmacarthur]

I tried to run the following on the playground to test what reqwest's default user agent was. See here

fn main() -> reqwest::Result<()> {
    let resp = reqwest::blocking::get("https://httpbin.org/user-agent")?.text()?;
    println!("{}", resp);
    Ok(())
}

I got the following error:

   Compiling playground v0.0.1 (/playground)
error: linking with `cc` failed: exit code: 1

ld terminated with signal 9

That rather looks like it was killed due to using too much memory. We limit the amount of memory available to the compiler process:

https://github.com/integer32llc/rust-playground/blob/163af6dab05b503a8cd1e7ea994b216d665bb48c/ui/src/sandbox.rs#L432-L433

We'd need to profile the cargo execution to know how much memory it takes to see if it's close enough that we could bump it up of if it's wildly egregious.

what reqwest's default user agent was

FWIW, I'm pretty sure there isn't one.

Yeah, I ran it locally afterward.

[zyctree]

jsut tried /usr/bin/time -v cargo run,
here is the output

Maximum resident set size (kbytes): 220032
