99.9% of the times someone reports something like this the problems are
outside of libcurl. It's either a memory system confusion/mixup (in windows),
usage of SSL multi-threaded without mutex callbacks set or otherwise ruining
memory from the app itself.

If you build just a sample app from docs/examples/ and run it, does it crash
too?
