Segmentation fault when trying to use secure-transport with curl 8.12.0 multissl #16253
Description
I did this
Configured and built curl with:
$ ./configure \
--with-secure-transport \
--with-openssl \
--with-default-ssl-backend=openssl
$ make
Ran curl and got:
$ CURL_SSL_BACKEND=secure-transport ./src/curl -q -s -v https://example.com/ >/dev/null
Segmentation fault: 11
Then I rebuilt curl with ./configure --enable-debug ..., the crash log shows:

My guess: Does vtls.c:918 need the same if(Curl_ssl->init) test as vtls.c:426?

I expected the following
Able to use secure-transport with multissl.
