Operating system: UnixWare 7.1.1
PHP version: 4.1.2
PHP Bug Type: Reproducible crash
Bug description: Reproducible segmentation fault in pages using oci8 (Oracle 8.1.7)
Hi!
we have
- SuperMicro P3TDLE, 2* Pentium III, 1 GB RAM
- UnixWare 7.1.1 with latest patches installed
- Apache 1.3.23
- PHP 4.1.2
- Oracle 8.1.7.2
- gcc 2.95.2
PHP was configured with command:
export ORACLE_HOME=/u01/app/oracle/product/8.1.7
export LD_LIBRARY_PATH=/usr/local/lib:$ORACLE_HOME/lib
./configure --with-oci8 --with-apxs --without-mysql --enable-sigchild
--host=i486-sco-sysv5uw7
We have found (at least) one php page using database connection (this page
is rather complicated, but we can provide it on demand), which generates
"Segmentation fault" reproducibly. It seems, that "Segmentation fault" is
caused by php, as it can be seen from following lines generated by gdb
session:
egg 174# gdb /usr/local/apache.dbg/bin/httpd
(gdb) run -X
Starting program: /usr/local/apache.dbg/bin/./httpd -X

Unfortunately, we are unable to configure PHP with --enable-debug option,
it crashes with "Segmentation fault" during Apache startup :-(
Can somebody help ?
