Join arr = test Join arr1 = test
On a vpinball where wine vbscript is embedded we get a segfault: free(): double free detected in tcache 2

--- Comment #1 from Nikolay Sivov bunglehead@gmail.com --- This is not specific to empty variants, Join() is not implemented at all.

--- Comment #2 from francisdb francisdb@gmail.com --- Sorry about the confusion.
Looks like vpinball implements the join. If the join not being implemented is on purpose I guess this can be closed?

--- Comment #3 from francisdb francisdb@gmail.com --- In case somebody wants to implement this
https://github.com/vpinball/vpinball/blob/9cd01e63b6271b2cc59a180a7335093b2c...
But keep in mind that this fails when the first item is empty. (will be fixed on a later commit at the vpinball side)

It's not on purpose, no. We'll need it implemented, with some tests.

In vpinball's implementation of GlobalJoin, we were forgetting to NULL out the conv_str in the loop.
This is fixed now. I'm sure if this was implemented in Wine, it would be done the right way. I took bits and pieces from all the other global string functions to hopefully make the code similar.
