P.S. I think you should also send a message to syphilis too about this last error.

Which error is that ?

I don't understand how it happens that the XS module Test::LeakTrace is fine for the OP, but the XS module List::MoreUtils::XS is not.
I keep thinking that should be giving us a clue ... but I don't see any clues.
I compared the way both modules built on the OP's perl-5.30.3 and both build in essentially the same way. In the (below) copy'n'paste, the first line of each pair of lines is from the Test::LeakTrace build, the second line is from the List::MoreUtils::XS build:

In both cases we see the same process, and the same flags - yet one results in a runtime mismatch and the other doesn't.
The L::MU::XS build inserts a -I. in a couple of spots (needed to load headers that are located in the L::MU::XS top-level source directory), and the T::LT build inserts a "-Iinc" in a couple of spots - but I don't see anything telling in those minor differences.
And, apart from those 2 minor discrepancies, the builds are identical.
How can one module incur a mismatch, and the other not ?

Cheers,
Rob

Sorry, it's not an error, it is just that he now runs perl 5.30 via perlbrew and compiles it with that (Re^6: XS.c: loadable library and perl binaries are mismatched (got handshake key 0xc100000, needed 0xc180000)). So yes, perhaps starting fresh from the beginning to see a) how it is compiled using the new settings (for example to confirm if correct binaries and library paths are used), b) where it fails if it does, c) strace output filtering out noise to see the fullpath of the library failing the handshake.

I will delete the perl and start over again after ensuring there are no environment variables that pertain to perl things (anything else I should consider there?) BTW, the messed up XS.c I posted the other day was due to a posting length limitation on this site. The site truncated the lion's share of the module and my closing code tag as well. FWIW, I edited that post to enter as much as I could without truncation. Sadly, the "preview" tool gives no indication of the truncation, so it all looked pretty rosy to me when I submitted it. Lesson learned Also, I just want you all to know how much I appreciate the time you are taking to help me out and, hopefully, others will be able to learn from this Rick One more thing... I'll be out for the remainder of the week and will pick this back up Monday	[reply]

BTW, the messed up XS.c I posted the other day was due to a posting length limitation on this site Bummer ... and the file is also too big for the public scratchpad, too. (I guess it's the same limit.) I'll msg you my email address, and you can send the file over if you like. (I still wouldn't mind seeing what, if any, difference exists.) Cheers, Rob	[reply]

One more thing to check perhaps is to create a fresh new user which also uses perlbrew and see if that makes a difference, i.e. if it's something in your current user settings / leftover libraries. Linux tip: if you manage to find a place to deposit large files with the output, then you can use the command `script outfile.txt` to capture all output including what you type at the ecommand line. When you are done, type `exit` and publish "outfile.txt" to say googledocs	[reply] [d/l] [select]

the messed up XS.c I posted the other day was due to a posting length limitation on this site. I'm about to post a discussion regarding the misleading preview of large posts. Thanks for bringing this to my attention. If you really need to post such large sections then your 2 main options are either to use an off-site location (like a pastebin or a Gitlab snippet or your own site, even) and link to that or else the old favourite of gzip and uuencode. (massive temporary code section removed) and the discussion is now here.	[reply]
