Failed to build on TravisCI with Crystal 0.27.1

[anykeyh]

Hello,

I've an issue with my build here: https://travis-ci.org/anykeyh/clear/jobs/488396058

Failed make bin:
/usr/bin/shards build 
Dependencies are satisfied
Building: ameba
Error target ameba failed to compile:
Unhandled exception: Overflow (OverflowError)
Failed to raise an exception: END_OF_STACK

I'm using crystal v0.27.1 and ameba v0.9

$ crystal --version
Crystal 0.27.1 [64137d045] (2019-01-30)
LLVM: 4.0.0
Default target: x86_64-unknown-linux-gnu

Any ideas? It works well on my dev machine. It might be related to LLVM since I'm using the 6.0 on my dev machine vs 4.0 on the travis build.

@anykeyh Relates to:

• OverflowError always lead to can't raise END_OF_STACK crystal-lang/crystal#7369
• Crystal 0.27.1 built with --release crashes immediately with OverflowError crystal-lang/crystal#7368

[anykeyh]

It's weird. I wonder if any other shards building ameba binary in Travis-CI experience the same problem?
Any work-around possible?

@anykeyh

• You can temporary switch to osx operation system on Travis

# .travis.yml
os: osx

or

• use this branch as a temporary workaround on Ameba's side:

development_dependencies:
  ameba:
    github: veelenga/ameba
    branch: crystal-0.27.1-workaround

The workaround itself: https://github.com/veelenga/ameba/compare/crystal-0.27.1-workaround

[veelenga]

@anykeyh please let me know if that helps.

[anykeyh]

It's good, I'll use the branch work-around until Crystal is fixed.

I had the same issue (on Travis) and the workaround fixed it for me 👍

[anykeyh]

EDIT: Nevermind 😅

Fixed with Crystal 0.27.2 released today 🎉

[veelenga]

Closing this now. Will not remove the workaround branch in case anyone uses it.
