Various Apaches (doesn't really matter) and MySQL 4.1.6-4.1.7.  The key
is PHP; really, only the PHP version in CVS (checkout HEAD) will work
correctly in detecting the right 64bit libs.

Yeah, ldd should give you some clues.  However, unless you're using PHP
from CVS (5.1) it might not be linking against what you expect,
especially when used with a lot of extensions.  What does your
./configure look like?  Perhaps you could strip to a bare minimum
./configure, then add extensions until things start to segfault again.
