Oh, thank you !!
That's helpful.

If you have any perls (the actual perl version is not important) built using earlier versions of a Microsoft Compiler, and those perls were also built with: 
ivtype='__int64'
ivsize=8

[download]
could you post the output of perl -V:ccversion for them ?

Somewhere between ccversion='16.00.30319.01' and ccversion='19.24.28316' a significant change in the MS C runtime occurred. (That change has relevance to List::Uniqnum.)
But I don't know exactly when that change occurred, and I'd like to find out.

Thanks again.

Cheers,
Rob
