OpenSSL::Provider does not automatically unload at shutdown, causing it
to be reported as a memory leak by memory leak checkers when using
RUBY_FREE_AT_EXIT. For example, LSAN reports many memory leaks that looks
like this:
#15 0x78dd17e2dfb4 (/lib/x86_64-linux-gnu/libcrypto.so.3+0x22dfb4)
#16 0x78dd17e2b195 in OSSL_PROVIDER_try_load (/lib/x86_64-linux-gnu/libcrypto.so.3+0x22b195)
#17 0x78dd35ba8751 in ossl_provider_s_load ext/openssl/ossl_provider.c:60:16
This commit adds a hook at shutdown to unload all the OpenSSL providers.

Ah looks like this issue was fixed in openssl/openssl@927d056 and included since OpenSSL 3.2.0. |
