s3: Fix a 64-bit BUG
Quick explanation why this is a problem: It is not safe to pass a pointer to a uint32_t into a routine that expects a size_t *. The routine that this pointer is passed to has no chance to find out that in reality it was passed a pointer to a uint32_t. On platforms where sizeof(size_t)==8, we get a nice overwrite of a stack area that should not be overwritten. As this happens over an over again: Does someone know a means to make gcc stop with an error in this case? Volker
