Summary0000844: dotty 2.2 fails with ''panic: (file mem.c, line 400, func allocbuffer) ..."

I'm using graphviz-2.2 from,
compiled using
./configure --prefix=/usr/public/graphviz-2.2; make; make install
Using a tiny file of less than 16MB, I get the following:
bash$ /bin/ls -s
bash$ wc -l
bash$ dotty
panic: (file mem.c, line 400, func allocbuffer) size is too big
Aborted (core dumped)

This appears to occur in lefty/mem.c. Backtrace:

Additional Information

Stack frames 0000004 and 0000005 contradict each other:
0000004 0x08058a5a in allocbuffer (size=32770) at mem.c:400
0000005 0x080582e1 in Mallocate (size=0) at mem.c:158
Mallocate calls allocbuffer with 'size=0' and it
appears as 'size=32770' in allocbuffer.

[erg] Not strictly a bug - lefty was built to use shorts as ints,
and the input graph causes this bound to be exceeded. Made the error
message clearer, and now build lefty using integer = int.
