Details

Calling curl_pause() results in a segmentation fault since Curl 7.69; version 7.68 works fine.

I have also tested curl-7.69.0-3 from [testing] which includes related patches but that crashes as well.

Run the attached file to reproduce. (On CLI php ./test.php)

Known related issues:
* This breaks libraries like symfony/http-client and probably others.
* Composer (with esp. flex) runs at 100% CPU usage and does not seem to terminate. (CI was killed after 6 hours)
   test.php (0.1 KiB)
This task depends upon

I know this is an upstream bug, but I'll also track it here as I am not sure if only the PHP module is affected or if it is curl bug.

Good news: I build the curl git master and that did not crash.
