Hi,
	I'm new to the newsgroup and I'm trying to debug PHP 6 on a test server
(x64 architecture).  However, for some unknown reason, it segfaults if I
try to run it with any files that work in PHP 5.2.0.

The segfault is at the end of most scripts, at the beginning of others.

The backtrace looks like this:
#0 _zend_mm_free_int (heap=0xb30330, p=0x377cff39f390d7e)
	at /root/php6/Zend/zend_alloc.c:1522
#1 0x00000000006a5cdf in destroy_op_array (op_array=0x2ab2aef29ff8)
	at /root/php6/Zend/zend-opcode.c:265
#2 0x00000000006b06d5 n zend_execute_scripts (type=8,retval=<value
optimised out>, file_count=3)
	at /root/php6/ZendSend.c:1665
#3 0x0000000000662763 in php_execute_script (primary_file=0x7ffffbb9d360)
	at /root/php6/main/main.c:1949
#4 0x000000000073d1c4 in main (argc=2, argv=0x7ffffbb9f5c8)
	at /root/php6/sapi/cgi/cgi_main.c:1656

This looks like a Zend issue trying to clean up after the running of a
program.

Can somebody please find a fix?  I'm willing to test a patch first
before it is committed.

Chris

Why do you do that? 
I mean, PHP6 is not even an alpha and it's too early to test it unless you're a developer.

I test it from time to time on both Linux 64bit machines I have and I have to 
say I can't reproduce any crashes.

What kind of OS is that (Solaris?)? What compiler did you use (GCC 4.1?)?

What's wrong with him trying to test it out? Let's not be so exclusive 
here.
