Of course it is. That's what SSL_shutdown() should get as input. You could set
a break-point there with your debugger and investigate the data at the moment
it crashes. Or you can run the test case with valgrind or similar to see if
you can catch some other kind of bad memory access or so.

Is it exactly those numbers every time? That feels like some kind of fixed
boundaries or limited-sized arrays or something that get hit. I don't mean
within libcurl then as it doesn't have any such.

So my advice is still to break-point at the point it crashes. The fact that it
repeats easily should also make debugging this fairly easy.

Or work on making an example program that repeats this behavior for us.
