Bug #43495 array_merge_recursive crash with recursive arrays
Submitted: 2007-12-04 11:25 UTC Modified: 2007-12-05 20:04 UTC

Status: Closed Package: Reproducible crash
PHP Version: 5.2.5 OS: any
Private report: No CVE-ID:

This is basically the same as bug 42752 but in the array_merge_recursive rather than the array_walk recursive code. The fix is the same.

The detection of recursion used in array_merge_recursive is incorrect so it is possible to pass recursive arrays that cause unbounded recursion, leading to stack overflow.

Reproduce code:



array_merge_recursive ($a,$b);
echo "reached the end \n";


Expected result:
reached the end

Actual result:
