    Hi @skunktoy which curl version do you have installed (original repo or from an alternative one like Remi's) ?

    Should just be the standard package and the devel package is from the appstream?

    Thanks for confirming. Would it be possible for you to try with a more recent curl version from a different repository ? It does not appear to me, at first at least, a PHP issue.

    Would you happen to have another repository you could recommend, or would just compiling the latest libcurl work?

    I do not see evidence of available more recent versions of curl in places I would expect (e.g. EPEL), so maybe yes if this is not problem you may try from sources.

    Have compiled curl 8.16.0, and have compiled php against it. Now running : make test

    And it failed to throw that error or a segfault.

    Guess I will try 7.88.1 and see what happens.

    I'm guessing I should be contacting Redhat Support to see if they will do anything at this point?

    Note for next time you can directly run an individual test or even just extension test suite with sapi/cli/php run-tests.php path to phpt unit test or extension directory.

    That might be a curl dependency issue instead then.

    I can reproduce on centos stream 9, tried to install the 10th version but it kernel panic directly .. unfortunately not the only one having this issue.To summarize, does not fail on my ubuntu laptop nor macos. I may try other scenarios such as having curl with a different tls backend (e.g. gnutls) on the centos instance.

    So I did try with curl 7.76.1 but with gnutls

    /home/dcarlier/CURL/bin/curl-config --configure
 '--with-default-ssl-backend=gnutls' '--with-gnutls' '--enable-debug' '--prefix=/home/dcarlier/CURL

    and built PHP linked to it

    Trying out with another openssl version/set of features (seems it s 3.5.1 on Centos while on my ubuntu it s 3.4.1 and macos 3.5.4) might be an option.

    I'm going to close this as I can't see how this could be PHP issue.
