It needs to handle memory allocation errors and return
LIBSSH2_ERROR_ALLOC when it happens. Something like this:
s = LIBSSH2_ALLOC(session, len);
if (!s) {
return _libssh2_error(session, LIBSSH2_ERROR_ALLOC,
"Unable to allocate memory for foo");
}

It can be issue under Windows when multiple runtime libraries are used
(one runtime library cannot free memory maintained by another runtime
library). The workaround is for the application to provide malloc/free
callbacks. Possibly libssh2 should have a 'libssh2_free' function.
