Description
I was playing around with #![recursion_limit] again, and then this happened:
thread 'rustc' panicked at 'failed to push initial stack frame: InterpErrorInfo { kind: reached the configured maximum number of stack frames, backtrace: None }', src/librustc_mir/transform/const_prop.rs:365:10
error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports
note: rustc 1.46.0 (04488afe3 2020-08-24) running on x86_64-unknown-linux-gnu
query stack during panic:
#0 [optimized_mir] optimizing MIR for `main`
#1 [collect_and_partition_mono_items] collect_and_partition_mono_items
end of query stackCode
#![recursion_limit = "0"]
