No backtrace:

Anything else?

This happened while tinkering with a code similar to this issue: https://github.com/rust-lang/rust/issues/107362

The difference is that I "manually unrolled" one level of Compose<F, Vec> into FVEC, so the type of Value<FVEC, Compose<F, FVEC, ()>> is now (possibly) an infinite chain of mutually recursive F and FVEC instead of a directly recursive chain of F

douglas-raillard-arm commented 1 year ago

Note that the crash happens after ~1min of grinding, so the rust playground unfortunately times out before that and simply kills rustc without giving the same SIGSEV result (you get SIGKILL instead).

albertlarsan68 commented 1 year ago

I was not able to reproduce the SIGSEV, but I got a SIGKILL after 13 minutes, with rustc using over 80GB of virtual RAM. output of time:

This has a particularly unpleasant impact from a user's perspective (continuing for a long time, increasing memory load, until there's a crash). It seems worth assigning the issue a priority in light of how hard it is for the a user to figure out what's going on.

WG-prioritization assigning priority (Zulip discussion).
