Hello, I am facing this problem where my application just terminates when I manually switch off my WiFi while it is waiting on curl_easy_perform() in a separate thread from the main thread.
Thread 4 "my-app" received signal SIGPIPE, Broken pipe. [Switching to Thread 0x7fffebfff700 (LWP 27283)] 0x00007ffff75364bd in write () at ../sysdeps/unix/syscall-template.S:84 84 ../sysdeps/unix/syscall-template.S: No such file or directory.

But as soon as I switch off my internet , my app terminates without even returning from curl_easy_perform. Any one got any ideas?
