('binary' encoding is not supported, stored as-is) ('binary' encoding is not supported, stored as-is) I find out that this is because I write the code in function. If I
write all curl code in main - it works fine without errors. But when
my code is in function in other cpp-file, when the progress_callback
returns non-zero it crashes. When it return 0 everything is fine.

everything works as it should be. The problem is when it returns
non-zero value. In documentation it is said that it will cancel the
request, and it dies so, but also program crashes.

Is it a divide by zero crash? Look what happens in your code when
utotal is 0.

this program crashed, but I receive the right output to the
