Substituting in my server info and a table I'm allowed to read, I've tested this snippet with the cli, apache1.3, and apache2. No segfaults whatsoever with php4 4.3.10-10. You're sure you've restarted apache after upgrading php4?
Sure I restarted Apache.
Here's a gdb backtrace of the crash, hope this helps a bit:
