New Comment:
no, that is not accepted by PCRE (the library used by PHP to handle the
regexes). anyway, most engines don't support more difficult
look-ahead/behind. Anyway, this is not a problem in PHP itself.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Description:
------------
The regex posted below is legal and fixed length but raises the
following warning:
lookbehind assertion is not fixed length
Situation: negative lookbehind contains a negated character class.
This bug makes it impossible to use a negated character class anywhere
within a negative lookbehind.
Reproduce code:
---------------
$regex = '/(?<=[^x])/';
