PHP compiles and installs fine on x86.  However, on my  
EV56 box, it completes the compile but then segfaults  
during "make install":

From the stack trace above, I gather that exactly 
0x100000000 is getting added to a couple of php_strspn's 
parameters.  Clearly something isn't quite 64-bit clean, 
but I don't know what's broken.  It could be the 
install-pear.php script, or it could be php itself...
