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.

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?

[devnexen]

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?
