Description:
------------
When I try to connect to a local Oracle 10g XE instance with oci_connect() I get a segfault. I found that I didn't have ORACLE_HOME set, however if I specify the character set UTF8, PHP segfaults. If I don't specify the character set, I get a warning about the environmental variable not being set.

Call to php_oci_init_global_handles should check that OCI_G(env) is not null before continuing

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.

--------

Fix merged to CVS.  Will be released in a (future) PECL OCI8 1.3.5.

The bug affected OCI8 when compiled with an ORACLE_HOME (not an Oracle Instant Client).

Not all cases of ORACLE_HOME being unset will be protected by the fix: don't do putenv('ORACLE_HOME=""') in a script.
