Description:
------------
When constants are registered while loading type libraries, the
constant names are always allocated persistenly, but the constants
themselves may be allocated non-persistently.

This issue has been introduced with commit 5eb1f92, and as such
does only affect PHP-7.3+.

Test script:
---------------
make test TESTS=ext\com_dotnet\tests\bug39606.phpt

Expected result:
----------------
Test succeeds even for debug builds

Actual result:
--------------
Test fails for debug builds with:

Assertion failed: !(zval_gc_flags((s)->gc.u.type_info) & (1<<7)), file zend\zend_string.h, line 290
