Crystal: LLVM - Assertion failed at `--release` build

[daniel-Q6wUOI]

So my command I want to execute and the followed error message:

daniel@daniel-fbFED23sd:~/projects/kemal$ crystal build src/server.cr --release
crystal: /var/cache/omnibus/src/llvm/llvm-3.8.1.src/lib/CodeGen/LexicalScopes.cpp:160: llvm::LexicalScope* llvm::LexicalScopes::getOrCreateRegularScope(const llvm::DILocalScope*): Assertion `cast<DISubprogram>(Scope)->describes(MF->getFunction())' failed.
/usr/bin/crystal: line 102: 15601 Aborted                 (core dumped) "$INSTALL_DIR/embedded/bin/crystal" "$@"

Infos:

• I installed crystal newly onto my system 1 hour ago, and installed all required libaries as it says in the wiki.
• crystal run src/server.cr works fine
• I am running Ubuntu 17.04

Can you provide the minimal source code that triggers this error?

As a temporary workaround until this is resolved you can just add --no-debug together with --release.

My source @bew

require "kemal"

get "/" do
    "Hello World!"
end

Kemal.run

@straight-shoota Workaround works find, didn't found the other issued 😞
