I tried my best on this one. Tested against the trunk:
svn info | grep Revision
Revision: 323476
I created a test file for this, will attach.
I ran the following with gdb:
$ gdb sapi/cgi/php-cgi
and then set a breakpoint
(gdb) break php_pcre.c:1318
finally ran the test script like:
(gdb) run run-tests.php ext/pcre/tests/bug53823.phpt
On https://gist.github.com/1904467 I c/p-ed some output from gdb, but that
might be incorrect as I'm fairly new to all this. Anyway, lines 12 and 22 in
that gist caught my attention.
Also, I think the same issue exists for preg_filter, too.

...and then I forget to change the *. Let's try that again...
These work as expected:
echo preg_replace('/[^\pL\pM]+/iu', '', 'áéÃóú');
echo preg_replace('/[^\pL\pM\pN]+/iu', '', 'áéÃóú');

A workaround is to use + instead of *.
These work as expected:
echo preg_replace('/[^\pL\pM]*/iu', '', 'áéÃóú');
echo preg_replace('/[^\pL\pM\pN]*/iu', '', 'áéÃóú');
