Hi,

Strawberry's PDL build ships with gsl-2.6. (The non-PDL build does not include a gsl library, and I'm guessing that installing PDL into the non-PDL build will not, of itself, install a locatable gsl library.)
It seems that both "(3)" and "(4)" are using gsl-2.6, whereas both "(1)" and "(2)" are avoiding the issue by installing and using gsl-2.7.1.

It could be that "(3)" and/or "(4)" did install 2.7.1 (I don't know) but they still find and use the buggy 2.6 version that shipped with Strawberry Perl-5.32.1.1-PDL.
You just need to ensure that the non-buggy 2.7.1 gets loaded and used.
At least, that's how it looks to me.

Cheers,
Rob
