Tried with rustc 1.32.0-nightly (65204a9 2018-11-12).
To reproduce:
- Clone https://github.com/osa1/tiny
cargo build --release && ls -lha target/release/tiny. You'll see a 2.4M binary.
- Apply this diff
diff --git a/src/lib.rs b/src/lib.rs

-static ALLOC: std::alloc::System = std::alloc::System;

extern crate quickcheck;
- Repeat the same command. The binary size is now 2.5M.
Originally reported on /r/rust thread.
The reason why I think this is a bug is because the default allocator should already be the system allocator, so overriding the allocator to system allocator should have no effect.
