gnuchess v2 on sco xenix

[The Super User]

I have been playing with the sources to gnuchess version 2 as recently
posted to comp.sources.games. I'm trying to get the program running on
SCO Xenix 286 (Development System 2.1.4g) and...

I have gotten through all of the infinite spill error problems in the
usual roundabout simplification way, and I've split the source files
in to: gnuchess.c became gcsplit[1234567].c and uxdsp.c became
uxdsplit[123].c.

Finally, everything compiles, but when I run the game, it crashes in
the routine GetOpenings() in uxdsp.c, right after the mallocs:

            entry = (struct BookEntry *)malloc(sizeof(struct BookEntry));
            mp = (unsigned short *)malloc((i+1)*sizeof(unsigned short));

The next line:

            entry->mv = mp;

is the line causing the crash. I've checked that "entry" and "mp" are
actually getting the memory they request; they are. (I have not checked
if the sizeof() operators are returning anything sane however.)

One last piece of information: the crash occurs the *first* time this
part of the routine is entered; e.g. if you put a printf() statement 
right after the malloc()'s above, you'll see it just once, then core dump.

Any help in getting this working would be appreciated (it compiled and
ran fine under BSD 4.3).

Thanks!
