see NixOS/nixpkgs#285264

Steps To Reproduce

1. checkout nixVersions.nix_2_20: init at 2.20.5; nixVersions.unstable: 2.19 -> 2.20 nixpkgs#285264
2. nix build .#nixVersions.unstable

Expected behavior

It should compile.

nix-env --version output

Additional context

I tried to compile it with boost 1.84 but that has the same problem.

Is this the same issue that led to #9512?

[trofi]

Also noticed the same build failure when tried to package nix in the distribution where boost-1.84 is the default.

[edolstra]

I think we can close this issue since it's a nixpkgs packaging issue.

[trofi]

The build failure is not nixpkgs-specific. Other Linux distributions are affected just as much.

[rhelmot]

I'm experiencing this with boost 1.83 on FreeBSD. I found that it is resolvable by switching to the latest release (8.2.6) of boehm-gc.
