I am still stuck on this :( It looks like I am building libcurl
correctly, yet it still crashes.

Would anyone know where I can get a pre-built libcurl (and openssl)
static library for VS2010 of 7.24.0?

I checked the pre-built binaries for the libcurl on the curl page, and
they are outdated for MSVC and I am not sure if theya re using MSVC
2010.

Thanks,
J
