Fixed in [f0a6d62a1ade872d]. With this fix, a library is only unloaded from the process if it provides a "Unload" function. Since it requires some care to produce a library fit for dynamic unloading, it makes sense to limit unload functionality only to those libraries specifically designed to support it. Checking for the existence of an "Unload" function is a good way to differentiate between modules that can be unloaded, and modules that cannot. jan.nijtmans added on 2022-04-14 10:33:21:
Since the fix is in core-8-branch now, this ticket can be closed. Thanks, pooryorick, for the fix! | ||||
