Prior to running the tests, the test runner checks for all generally available extensions; it does this by scanning the `extension_dir` for files matching the typical extension pattern, but verifies that the file is actually a PHP extension by calling `dl()`. However, `dl()` has known issues[1]. On Windows CI we always get an ugly "zend_mm_heap corrupted" message, and we even can't `dl()` ext/mysql when OPcache is enabled[2]. So we better avoid the double-check with `dl()`, which is unlikely to be necessary anyway. [1] <php#9196> [2] <php#8508>

There was a problem hiding this comment.
I agree with this, especially if we want to remove dl in the future.

It seems this patch uncovered an issue with our PDO_Firebird builds on x86 Windows; previously, they were skipped, now they fail because pdo_firebird.dll can't be loaded. I'll have a look soon. (cc @iluuu1994) PS: see #16223. |
