oci8-1.2.2 segfaults on Solaris10/x86

Hi. I'm trying to get php4 going on Solaris10/x86 and I'm not finding this an easy task. I built php-4.4.4 (using the Sun compilers) and then tried to build the oci8 module which I downloaded from pecl.php.net. After building and installing thisthough, I find I get a segfault whenever I try to run a trivial test program against our test database: <?php $conn = ocinlogon("XXXXXXXX", "XXXXXXXX", "CMSZ"); ocilogoff($conn); ?> I ran this by doing a simple /usr/local/php-4.4.4/bin/php -f oci-test.php The stack trace using the core file shows: (gdb) bt warning: (Internal error: pc 0x0 in read in psymtab, but not in symtab.) warning: (Internal error: pc 0x0 in read in psymtab, but not in symtab.) #0 0x00000000 in ??

Any ideas what the problem here might be? Is there a known combination of php4/oci drivers that will work on Solaris10/x86? Regards, Robert.
