Indeed, I made a small mistake, it is Chameleon 3.8.1 that I am using.
I redid the tests and the consequences are serious because the code stops my Zope5 instance.
Below is the traceback:

I have emptied the Chameleon cache and the result is the same
Here is the code I made for my tests:
This one works:
My macro :
<metal:x define-macro="base">
<!doctype html>
< html lang="fr">
< head>
< meta charset="UTF-8" />
< meta name="viewport" content="width=device-width, initial-scale=1.0" />< /head>
< body class="bg-black bg-cover bg-no-repeat bg-top overflow-hidden" tal:define="T python:'toto'">
< div class="w-screen h-screen overflow-x-hidden overflow-y-auto">
< tal:x metal:define-slot="base-container"><tal:x content="T"></tal:x></tal:x>
< /div>
< /body>
< /html>
< /metal:x>
my page calling my macro and using the variable T defined in the macro :
<metal:x use-macro="context/base.html/macros/base">
<metal:fill fill-slot="base-container">
<tal:x content="T"></tal:x>< br>
appel direct dans la page template utilisant la macro
</metal:fill>
</metal:x>
and below the code that crashes my instance:
<metal:x use-macro="context/base.html/macros/base">
<metal:fill fill-slot="base-container">
<tal:x content="structure context/pushComponent.html"></tal:x>< br>
Injection d'une page template "pushComponent.html"
</metal:fill>
</metal:x>
With this code in the component :
<tal:x content="T"></tal:x>< br>
Appel dans un composant
I will refer this problem to the author of Chameleon but if you have any ideas.
Thanks
