PHP Bug Type: Reproducible crash
Bug description: Segmentation fault during tidy->parseString
Description:
------------
Hi,
If I compile PHP --with-tidy version from debian lenny libtidy-dev
20081224cvs-1, I get segementation fault on method
parseString().
My configure command is:
./configure --with-gmp --with-iconv=/usr/local/libiconv-1.11/ --with-imap
--with-imap-ssl --with-interbase --with-tidy --enable-debug
--with-kerberos
What I found and may be useful:
- If I don't compile it --with-gmp , the segfault doesn't ocur
- If I use libtidy-dev version from debian squeeze, it segfault too
- If I use php version 5.2.8, it segfault too
- If I use libtidy-dev from oldstable debian , the segfault doesn't ocur
- It segfault both in command line and apache (if it's compiled)
- It crash on whatever string - could be empty '', or some longer text
If more info needed, please let me know.
Ondrej

'output-xhtml' => true,
'show-body-only' => true,
), 'utf8');
Expected result:
----------------
some parsed string
Actual result:
--------------
