Bug description: Crash in Tomcat with PHP/Servlet feature

Trying to get PHP built on AIX with the IBM C compiler.

The setup I used is as follows:

CC=xlc_r
CFLAGS="-ma -g -Dinline= "
CXX=xlC_r
./configure --without-xml --without-mysql --with-servlet --with-java
The JDK level is IBM118.

Had to hack servlet.c and ext/java/config.m4 to make sure the
compile and link work. The change needed to servlet.c is to
rename the sapi_module structure to sapi_module_servlet since
the IBM compiler doesn't allow duplication of struct names. The
ext/java/config.m4 fix is to make it look for libjava.a instead of
the hardcoded libjava.so.

The configure/make/install work with the above setup although
there are quite a few warnings about type conversions and invalid
suffix (.lo).

Start Tomcat and attempt to invoke a PHP file and get a core
and a stack dump which points at open_file_for_scanning.
I tracked it down to the first instantiation of the
istdiostream class. More specifically, in zend_language_scanner.l >>
open_file_for_scanning() in the ZEND_HANDLE_FP case
(ZTS). The file_handle and file_handle->handle.fp are not
null but the file_handle->handle.is assignment never completes.

The native stack contains:

open_file_for_scanning
compile_file
zend_execute_scripts
php_execute_script
Java_net_php_servlet_send

Called from net.php.servlet.service() in Java.
