When asking such questions, please include the part of the source code in
question. One thing you must remember here is that some pointers provided
to the LoadSeg() function are BCPL pointers, called BPTR's. If these pointers
do not point to long-word aligned buffers, then the first word of your buffer
risks getting overwritten.
