No, changing
php_error_docref(NULL TSRMLS_CC, E_STRICT, DATE_TZ_ERRMSG "We
selected '%s' for '%s/%.1f/%s' instead", tzid, ta ? ta->tm_zone :
"Unknown", ta ? (float) (ta->tm_gmtoff / 3600) : 0, ta ? (ta->tm_isdst ?
"DST" : "no DST") : "Unknown");
to
double value = (double) (ta ? (float) (ta->tm_gmtoff / 3600) : 0);
php_error_docref(NULL TSRMLS_CC, E_STRICT, DATE_TZ_ERRMSG "We selected
'%s' for '%s/%.1f/%s' instead", tzid, ta ? ta->tm_zone : "Unknown",
value, ta ? (ta->tm_isdst ? "DST" : "no DST") : "Unknown");
does not change anything.

Have you tried changing the (float) cast to (double) ?

So it's actually bug in ext/date..

When cross compiled for ppc_85xxDP
A. '<?php phpinfo(); ?>' terminates after displaying the date info and
displays error 'Fatal error: Balloc()
allocation exceeds list boundary in
/media/server/wwwroot/htdocs/info.php on line 2'
B. 'php -i' terminates after displaying the date info and terminates
Workaround:
If I replace %f by %d in the call to php_error_docref() in function
ext/date/php_date.c::guess_timezone():
php_error_docref(NULL TSRMLS_CC, E_STRICT, DATE_TZ_ERRMSG "We
selected '%s' for '%s/%.1f/%s' instead", tzid, ta ? ta->tm_zone :
"Unknown", ta ? (float) (ta->tm_gmtoff / 3600) : 0, ta ? (ta->tm_isdst ?
"DST" : "no DST") : "Unknown");
replaced by
php_error_docref(NULL TSRMLS_CC, E_STRICT, DATE_TZ_ERRMSG "We
selected '%s' for '%s/%d/%s' instead", tzid, ta ? ta->tm_zone :
"Unknown", ta ? ta->tm_gmtoff : 0, ta ? (ta->tm_isdst ? "DST" : "no
DST") : "Unknown");
this error disappears.
'php -i' will call guess_timezone() which calls
php_error_docref(NULL TSRMLS_CC, E_STRICT, DATE_TZ_ERRMSG "We selected
'%s' for '%s/%.1f/%s' instead", tzid, ta ? ta->tm_zone : "Unknown", ta ?
(float) (ta->tm_gmtoff / 3600) : 0, ta ? (ta->tm_isdst ? "DST" : "no
DST") : "Unknown");
which ends up calling
xbuf_format_converter() which does a va_arg(ap, double) for the %f
passed in to php_error_docref()
if I replace
case LM_STD:
fp_num = va_arg(ap, double);
by
case LM_STD:
fp_num = va_arg(ap, float);
I get
/home/christoph/php/ppc/php-5.2.8/main/spprintf.c: In function
'xbuf_format_converter':
/home/christoph/php/ppc/php-5.2.8/main/spprintf.c:570: warning: 'float'
is promoted to 'double' when passed through '...'
/home/christoph/php/ppc/php-5.2.8/main/spprintf.c:570: warning: (so you
should pass 'double' not 'float' to 'va_arg')
/home/christoph/php/ppc/php-5.2.8/main/spprintf.c:570: note: if this
code is reached, the program will abort
Reproduce code:
---------------
'php -i', <?php phpinfo(); ?>
You will need to cross-compile PHP with the ELDK-4.2 for ppc_85xxDP and
run on the target ppc
X. Install ELDK-4.2
Note: ELDK does not require *any* root privileges, which is why I run
everything from my home dir.
X.1 download ELDK-4.2:
ftp://ftp-stud.hs-esslingen.de/pub/Mirrors/eldk/4.2/ppc-linux-x86/iso/ppc-2008-04-01.iso
and burn CD
X.2 install ELDK-4.2: /media/ppc-2008-04-01> ./install -d
/home/christoph/ELDK-4.2 ppc_85xxDP
X.3 set environment variables in normal Linux shell (2 exports)
export CROSS_COMPILE=ppc_85xxDP-
export
PATH=/home/christoph/ELDK-4.2/usr/ppc-linux/bin:/home/christoph/ELDK-4.2/usr/bin:/home/christoph/ELDK-4.2/bin:$PATH
A. cross-compile apache from ELDK-4.2 src rpm for ppc_85xxDP
Do A. if you want to call '<?php phpinfo(); ?>' from a browser
If you only want to execute 'php -i', you can skip this step A.
A.1 Do X.3 first
A.2 download and copy apache source rpm
'ftp://ftp-stud.hs-esslingen.de/pub/Mirrors/eldk/4.2/ppc-linux-x86/sources/target/SRPMS/httpd-2.2.4-4.1.src.rpm'
to /home/christoph/ELDK-4.2/usr/src/denx/SRPMS
> cd /home/christoph/ELDK-4.2/usr/src/denx/SRPMS
> ~/ELDK-4.2/usr/src/denx/SRPMS> ${CROSS_COMPILE}rpm -iv
httpd-2.2.4-4.1.src.rpm
A.3 build apache
cd > /home/christoph/usr/src/denx/SPECS
~/ELDK-4.2/usr/src/denx/SPECS> ${CROSS_COMPILE}rpmbuild -ba httpd.spec
A.4 install apache to /home/christoph/ppc/wwwroot
B. cross-compile PHP-5.2.8 for ppc_85xxDP
B.1 download and copy PHP sources to /home/christoph/php/ppc/php-5.2.8
B.2 build php
B.2.1 If you executed step A. before, run
/home/christoph/php/ppc/php-5.2.8> ./configure --build=i386-linux
--host=ppc-linux \
--with-apxs2=/home/christoph/ppc/wwwroot/bin/apxs \
--with-config-file-path=/media/server/wwwroot/php \
--disable-all \
--prefix=/home/christoph/ppc/wwwroot \
--enable-session
B.2.2 If you only want to run 'php -i' (and not '<?php phpinfo(); ?>',
so no libphp5.so is built) and you skipped step A., run
./configure --build=i386-linux --host=ppc-linux \
--with-config-file-path=/media/server/wwwroot/php \
--disable-all \
--prefix=/home/christoph/ppc/wwwroot \
--enable-session
B.3 install php to /home/christoph/ppc/wwwroot
/home/christoph/php/ppc/php-5.2.8> make install
B.4 go to your ppc target hardware and copy or mount directory
/home/christoph/ppc/wwwroot
B.5 on the ppc target hardware, execute 'php -i' or call <?php
phpinfo(); ?> from apache
Expected result:
----------------
Expected result:
'php -i' and <?php phpinfo(); ?> should display everything up to the
license info at the end.
Actual result:
--------------
Actual result:
Error 1: 'php -i' will not display anything after 'date' info

===========
Error2: when calling a info.php with this contents:
<?php
phpinfo();

anything more:
