Okay, so I'm closing this ticket. Please re-open if you'll find
that PCRE 8.38 won't solve the JIT related issue.

Hello,
Sorry for the delay.
Disabling the jit options does the trick. Indeed, my version of PHP7 was bundled with PRCE 8.35.
I'll ask the package's maintainer to update it.

This issue may be caused by pcre.jit=1. Please try with
pcre.jit=0. Also check PCRE_VERSION; 8.35 is known to cause some
issues regarding the JIT. Try with 8.38.

Thank you for your answer.
As you may have guessed, this is a regexp used to parse BBCode in a forum script. Every time the
parser is called, the page crashes, hence any input seems to trigger the bug.
I have tried with a simple dot (.), crashes too.
