Hello!
I am almost certain I am hitting some kind of bug. All of a sudden, array()
stops returning an empty array and starts returning something weird. The weird
thing behaves as NULL in most circumstances (e.g. gettype() says NULL),
except:
$foo=array(); // <-- weird thing returned
$foo[]="bar";
causes "Fatal error: [] operator not supported for strings", which is different
from the regular behavior of:
$foo=null;
$foo[]="bar"; // <-- $foo simply becomes an array
The problem is not limited to one place in code, and indeed before the fatal
caused by append-assignment I get several warnings like "array_diff_key():
Argument #1 is not an array", where the offending argument receives a result of
array().
The effect is not random, i.e. it always breaks identically when the same
script processes the same data. However I was so far unable to create a
minimal test case that triggers the bug. My script is rather involved, and
here are some things it uses:
- Exceptions
- DOM to-fro SimpleXML
- lots of multi-level output buffering
Disabling Zend Optimizer doesn't help. Disabling Zend Memory Manager is
apparently impossible. Memory usage is below 10MB out of 128MB limit.
Any similar experiences? Ideas what to check for? Workarounds?
