Ilia, the fix wasn't enough? There have also been other reports with
Apache 2.0.55..

The fix applied for this fixes the segfault for Apache 2.0.54.
Apache 2.0.55, however, still segfaults for the same SSI pages. I
recompiled php with the same configure options as before.
gdb backtrace is:
#0 0xb7de28dd in yy_push_state (new_state=1)
at Zend/zend_language_scanner.c:5760
5760 yy_start_stack[yy_start_stack_ptr++] = YY_START;
(gdb) bt full
#0 0xb7de28dd in yy_push_state (new_state=1)
at Zend/zend_language_scanner.c:5760
new_size = Variable "new_size" is not available.
Thanks! Especially for the first fix!

Description:
------------
SSI files which include php scripts are behaving differently after
upgrading from php 4.3.10 to php 4.4.1.
Apache version is 2.0.54.
I tried it with two different configure options:
./configure --with-apxs2=/usr/local/apache2/bin/apxs --enable-debug=no
--enable-versioning --enable-track-vars --with-openssl
--with-jpeg-dir=/home/sys/src/jpeg-6b --with-expat=/usr/lib
--with-mcrypt --with-config-file-path=/home/sys/etc/php-noZend/
--with-png-dir=/usr --with-zlib-dir=/usr --with-ttf
--with-freetype-dir=/usr --with-curl --with-mysql=/usr --with-gd
--with-sablot --with-xslt-sablot --enable-xslt
--disable-zend-memory-manager
./configure --with-apxs2=/usr/local/apache2/bin/apxs --enable-debug=no
--enable-versioning --enable-track-vars --with-openssl
--with-jpeg-dir=/home/sys/src/jpeg-6b --with-expat=/usr/lib
--with-mcrypt --with-config-file-path=/home/sys/etc/
--with-png-dir=/usr --with-zlib-dir=/usr --with-ttf
--with-freetype-dir=/usr --with-curl --with-mysql=/usr --with-gd
--with-sablot --with-xslt-sablot --enable-xslt
I also tried it both with Zend optimizer enabled and with Zend
optimizer disabled in php.ini.
Reproduce code:
---------------
The includes from the files which segfault look like:
<!--#include file="eventsdb.php?ID=81&fld=2" -->
The php code is a short db query:
if ($conn == false){
echo mysql_errno() . ": " . mysql_error() . "<BR>";
exit;
}
else {
$rtn = mysql_select_db ("[tablename]");
$sql = "select * from events where ID = ".$ID;
$result = mysql_query ($sql);
if ( ($row = mysql_fetch_row($result)) && ($today<=$row[4]
) ){
mysql_fetch_row($result)) {
[snip echo mysql results]
}
}
}
}
Expected result:
----------------
Results from mysql query should be displayed on page.
Actual result:
--------------
Blank pages.
The backtrace is the same regardless of which compile options I used:
#0 0xb7e095cc in zend_hash_index_update_or_next_insert (ht=0xb7ea29c0,
h=0,
pData=0xbfffdc60, nDataSize=12, pDest=0x0, flag=1)
at /home/sys/src/php-4.4.1/Zend/zend_hash.c:390
390 p = ht->arBuckets[nIndex];
(gdb) bt full
