Hey, was just taking a look at Rapi::Blog and ran into this issue in rabl.pl with perl 5.24.0

% rabl.pl create RABLTest

[vanstyn]

Can someone check and confirm if this is an issue on 5.26 specifically? Does it happen under 5.24 or 5.22?

[zl3ag]

Happening for me on 5.24.1, Debian Stable.

[joshrabinowitz]

yeah, my example shows it happening in 5.24.0

This has been tracked down to a breaking change in recent versions of Hash::Merge which breaks DBIx::Class::Schema::Loader (which is actually an even much bigger problem than this ticket). A patch has already been submitted and will hopefully ship to cpan very soon:

https://github.com/dbsrgits/dbix-class-schema-loader/pull/16

In the meantime, you can solve/confirm the problem by downgrading your version of Hash::Merge

[moussaid521]

Hi Henry,

I've downgraded to Hash::Merge 0.200 and it's working just fine.

Thanks Man!
