Getting weird Windows-only failures on 0.6.0

[svenstaro]

So I'm getting this failure that has something to do with vt100 but only on Windows: https://travis-ci.com/svenstaro/mt940-rs/jobs/179388389

I don't really understand it but it keeps me from upgrading for now. Maybe you can take a look?

I'm having the same problem: https://travis-ci.org/orium/rpds/jobs/496248771#L187

Thanks for the bug report.

We introduced vt100 dependency with PR #28. It's source code is super simple. The panic occurs in this line:
https://github.com/Phundrak/output-vt100-rs/blob/master/src/lib.rs#L36

thread '<unnamed>' panicked at 'assertion failed: `(left != right)`
  left: `0`,
 right: `0`', C:\Users\travis\.cargo\registry\src\github.com-1ecc6299db9ec823\output_vt100-0.1.1\src\lib.rs:36:5

@Phundrak can you have a look at this?
Would it be feasible to make your library more failsafe (not panicking)? E.g. by delegation of error handling try_init() -> Result<_,_> or something similar.

Otherwise I'd make this opt-in only for the time being.

I think the issue is that CI systems typically redirect the executable output through a pipe and the system calls expect stdout to be a console. This also occured on AppVeyor.

Anyways as suggested, I'll add a try_init that doesn't panic.

[nbouteme]

It's done. Unfortunately I can't publish the new output_vt100 version to crates.io, as @Phundrak has yet to add me as an owner, and he hasn't been responding to my messages lately.

[colin-kiegel]

fix is out with v0.6.1

thx @nbouteme for your quick support :-)

[svenstaro]

Working fine, thanks guys!
