Bug description: 500 Server Error on array_merge of func return
Description:
------------
If I do
{
$from=getarray();
$tgt=array_merge($to,$from);
}
all is well. But if I do
{
$tgt=array_merge($to,getarray());
}
then the page blows up with a 500 internal server error (and getarray() is
never called).
I can't (yet) duplicate this as a simple test case; it only happens in the
middle of a large site source base.
This is on an Apache server (1.3.37) with PHP 5.2.1 running as CGI.
The *really* painful part is the 500 Internal Server Error, with no PHP
error messages of any kind. Made it incredibly painful to track this down
;)
Reproduce code:
---------------
See above. I've not yet got a simple test case. All of the following
produce the 500 error:
$tgt=array_merge($to,getarray());
$tgt=array_merge($to,$from=getarray());
$tgt=array_merge($to,(array)getarray());
Only if the getarray() call is outside the array_merge() does it succeed.
Expected result:
----------------
a) No error
b) Better debugability of 500 Internal Server Errors caused by PHP
Actual result:
--------------
500 Internal Server Error with no other message.
