Re^2: Problem with XSLoader in Dumper.pm while using coverage

Thank you for the help but I don't understand why it mixes the Perl versions. This only happens when I set the env DEVEL_COVER_DB_FORMAT to be JSON.

It probably happens because that causes `Data::Dumper` to be loaded for some irrelevant reason. You will need to install parallel copies of `Devel::Cover` with each version of perl that your tests use. If you want to combine the databases, you will probably need to install the same version of `Devel::Cover` with each version of perl. For that matter, why do you want to combine coverage results from multiple versions of perl? I could see wanting to test code with multiple versions, but then you should strive for full coverage for each version, not full coverage across all versions.	[reply] [d/l] [select]
