I'm having exactly the same issue. PHP compiled for mips64 architecture, 32bit N32 binary format.

I've crossbuilt PHP from 5.3.20 to 5.3.27 and 5.4.20, both all crashes at the same point

1: how to test:
php -r 'print_r(date('l'));'



crashes with the following output

(gdb) run -r 'print_r(date('l'));'
Starting program: /root/php -r 'print_r(date('l'));'
*** Error in `/root/php': free(): invalid next size (fast): 0x10566ef0 ***

Nevermind.

Solved it by forcing ac_cv_c_bigendian_php=yes

Looks like a problem with autoconf detecting architecture when crosscompiling

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

Cross compiling is not supported, so you're on your own there. Marking this as "not a bug".
