Re: pl/perl extension fails on Windows

Hi,

I built PG17 rc1 using meson on Windows with the option "-Dplperl=enabled" . When I tried to create the extension,it crashed the database.

--

postgres=# create extension plperl;
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.

The log contains the following error.

src/pl/plperl/Util.c: loadable library and perl binaries are mismatched (got first handshake key 0000000012d00080, needed 0000000012c00080)

This issue is seen with strawberry perl 5.40 not with 5.38 . The Perl that is used during compilation and on the target machine is the same.

I have used strawberry perl 5.40 , which is available in the strawberry perl  home page ,but  5.40 is not available in the release page . So, is it recommended to use  perl 5.40 ?

Please let me know if you need any other information.

We've seen similar things before. See for example:

https://postgr.es/m/c2da86a0-2906-744c-923d-16da6047875e@dunslane.net

This looks like we are defining something we should not be, or not defining something we should be. We just need to find out what it is :-)

In the meantime, I would suggest sticking to 5.38.

cheers
