link_dead_code flag breaks sodiumoxide build

[andoriyu]

When trying to disable dead code elimination project fails to build.

To be clear, this works:
cargo test --no-run
this doesn't:
RUSTFLAGS=-Clink_dead_code cargo test --no-run

Build log:

error: linking with `cc` failed: exit code: 1

@andoriyu & @sreekanthn, can you tell us why you are compiling with -Clink-dead-code? That would help us in determining the priority of investigating this issue.

[sreekanthn]

Hi Micheal For me, the error appears when I tried to build the SDK of the project : https://github.com/hyperledger/indy-sdk So I am unable to answer why this flag has been turned on by the build script in this SDK thanks Sreekanth

In my car it's just to get better test coverage information.

Thanks for the feedback. We'll discuss it in the next @rust-lang/compiler meeting.

[deerdear]

@sreekanthn I've got the same problem. Any luck solving it so far?

[nikomatsakis]

Can one of you two try to go back in time and see if your project works with an older release? It'd be good to try and get an idea if this is a long-standing bug or a recent regression. Also, any attempt to minimize the test case that is broken would be most welcome. =)
