rustc uses a constantly increasing amount of memory up to OS crash or OOM kill #128365
Description
Clone the bug branch of webgraph-rs and run a check:
git clone [email protected]:vigna/webgraph-rs
cd webgraph-rs
git checkout bug
cargo c
On MacOs 14.5 (M1), nixos 23.11, and Fedora 38 the compilation process stops at this message:
Building [=======================> ] 207/209: webgraph
At this point, rustc uses a constantly increasing amount of memory. The result is an OS crash in MacOS, and OOM-kill on Linux.
The problem appears both in stable and nightly.
