Subject: [PATCH] Improve PHP object creation
|
|
|
4d4cd5 |
|
|
|
4d4cd5 |
Reportedly the code we were using in the directorin case gave segfaults
|
|
|
4d4cd5 |
in PHP 7.2 and later - we've been unable to reproduce these, but the new
|
|
|
4d4cd5 |
approach is also simpler and should be bit faster too.
|
|
|
4d4cd5 |
|
|
|
4d4cd5 |
Fixes #1527, #1975
