Tried the CVS snapshot PHP 5.2.2-dev 200702121730 - same 
result...

Works perfectly fine on Linux.
 [2007-02-12 23:10 UTC] nlopess@php.net 
can you please try with libtidy from cvs (http://sf.net/cvs/?group_id=27659) please? libtidy uses php emalloc calls, so it is probable that the error is in tidy itself.
(I couldn't try myself yet, because my other pc is not on-line..)

Also cannot reproduce on Solaris 8 (using libtidy from CVS).

The error is libtidy related. Thanks for your help!
