Hi Andreas,

By looking for my bug in RT, I just saw your answer, for an unknown 
reason, I didn't received it by email.

I confirm that your simpler version of the test case reveals the same 
bug, and I also confirm that your proposed workaround (adding
BEGIN { ${^RE_TRIE_MAXBUF}=-1; }
line), works in the initial program from which I extracted the test case.

So thank you very much from your help.

Where should I look to know in which version of perl this will be 
corrected ?

Does the workaround have an impact on some functionality or speed ?

Best regards.
