Description:
------------
I'm not to duplicate bug 42975, I just want to reopen that bug but found I (non developers) don't have that permission?

http://bugs.php.net/bug.php?id=42975

I also met this problem with php-5.2.9

'./configure' '--host=powerpc-linux' '--prefix=/usr'
'--with-config-file-path=/etc' '--disable-cli' '--disable-ipv6'
'--disable-all' '--enable-fastcgi'

the index.php file only contains one phpinfo(), and it tells

...

date

Fatal error: Balloc() allocation exceeds list boundary in
/vra/www/index.php on line 1
date/time support 	enabled
"Olson" Timezone Database Version 	2009.1
Timezone Database 	internal



I have also tried the CVS snapshot today, 2009-04-16

  http://snaps.php.net/php5.2-latest.tar.gz
 
it still have the problem, with the phpinfo() output, the date function
still have the fatal error:

PHP Version 5.2.10-dev

System 	Linux canyonlands 2.6.25 #2 Mon Apr 13 11:16:43 CST 2009 ppc
Build Date 	Apr 16 2009 12:16:06
Configure Command 	'./configure' '--host=powerpc-linux' '--prefix=/usr'
'--with-config-file-path=/etc' '--disable-cli' '--disable-ipv6'
'--disable-all' '--enable-fastcgi'
Server API 	CGI/FastCGI
Virtual Directory Support 	disabled 

date

Fatal error: Balloc() allocation exceeds list boundary in
/root/index.php on line 1
date/time support 	enabled
"Olson" Timezone Database Version 	2009.6
Timezone Database 	internal



Reproduce code:
---------------
compile php-5.2.9 or the cvs-snapshot tarball, on powerpc platform, get the php-cgi and combined it with lighttp, write a phpinfo() test page,

the date will run with fatal error.

Actual result:
--------------
date

Fatal error: Balloc() allocation exceeds list boundary in /root/index.php on line 1

that's really a fatal error on powerpc linux, please help to fix it, if you don't have that hardware, I can also help to fix it, I have greped the problem source is in Zend/zend_strtod.c, please give some hints on how to resolve,

Zend/zend_strtod.c:

$ grep -RsInw Balloc Zend/
Zend/zend_strtod.c:470:static Bigint * Balloc(int k)
Zend/zend_strtod.c:476:		zend_error(E_ERROR, "Balloc() allocation exceeds list boundary");
Zend/zend_strtod.c:487:			zend_error(E_ERROR, "Balloc() failed to allocate memory");
Zend/zend_strtod.c:522:	r = (int*)Balloc(k);
Zend/zend_strtod.c:570:			b1 = Balloc(b->k+1);
Zend/zend_strtod.c:658:	b = Balloc(1);
Zend/zend_strtod.c:686:	c = Balloc(k);
Zend/zend_strtod.c:757:	b = Balloc(k);
Zend/zend_strtod.c:761:	b = Balloc(k+1);
Zend/zend_strtod.c:839:	b1 = Balloc(k1);
Zend/zend_strtod.c:922:		c = Balloc(0);
Zend/zend_strtod.c:935:	c = Balloc(a->k);
Zend/zend_strtod.c:1110:	b = Balloc(1);
Zend/zend_strtod.c:1112:	b = Balloc(2);
Zend/zend_strtod.c:1917:			mhi = Balloc(mhi->k);
Zend/zend_strtod.c:2310:		bd = Balloc(bd0->k);

Today I noticed something maybe important:

if I delete /etc/localtime, or use a UTC timezone in /etc/localtime,

the phpinfo() function would display the default timezone is UTC,

Default timezone 	UTC

and no errors,

my previous timezone in using is copied from /usr/share/zoneinfo/Asia/Hong_Kong, maybe this cause the bug?

I have checked compiled php-5.2.10 for powerpc-linux cross compilation, the result is the bug still exists,

date() function is still broken through php-5.2.9 to 5.2.10, OS is powerpc-linux embedded system.

Subject: php库的问题我这边已经解决了，你试一下啊？
To: Cheng Renquan <crquan@gmail.com>

在编译的时候加入一个变量即：
#ac_cv_c_bigendian_php=yes ./configure --enable-embed=shared
--with-apxs=/usr/local/apache/bin/apxs
你试试看啊！
