seg fault in zend_hash

I was just wondering if i should report this as a bug? I have the latest CVS 5.1 code, and i can build it ok, but when PHP segfaults on startup. I am using Ubuntu Hoary on a P4. ./configure --prefix=/usr/local/php5 --with-config-file-path=/usr/local/php5/lib make The SAPI's build ok, but if i run the CLI through GDB i get this error when it starts: ------------------------------------------------------------------------------------ This GDB was configured as "i386-linux"...Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".
