Error OpenSSL Shutdown while in init - cURL - MSSQL about msphpsql

[v-makouz]

It seems likely that curl also loads OpenSSL, just like the ODBC Driver and there is probably some interference there. I'm having a bit of trouble getting php-curl to work to verify, but the fact that error goes away when CURLOPT_SSL_VERIFYPEER is set to false, strongly suggests that curl's use of OpenSSL is involved. I will investigate further.

By the way, do you know which version of OpenSSL is used there?

thanks ! Yes we used OpenSSL 3.0.2 15 Mar 2022 (Library: OpenSSL 3.0.2 15 Mar 2022)

Can you strace a successful run and the one with the error? Something like strace -o output.txt -f php file.php if it's run directly.

I can now run the repro code, but I don't get the same error, since I don't have the API URL setup that would return "certificate not allowed", if I understand the setup correctly.

The error is triggered before the API call. I got the error even when https://www.google.fr is set as the API URL. Are you sure you are using the same set up ?

Great, thanks. I'll see what I can find in those

Hi, turns out this is a bug in libcurl. More details here. They have fixed it for curl>=8.3.0. After upgrade the driver no longer throw an error.
