+Subject: [PATCH] mat4/mat5: fix int overflow in dataend calculation
+The clang sanitizer warns of a possible signed integer overflow when
+calculating the `dataend` value in `mat4_read_header()`.
+ 
+```
+src/mat4.c:323:41: runtime error: signed integer overflow: 205 * -100663296 cannot be represented in type 'int'
+SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior src/mat4.c:323:41 in
+src/mat4.c:323:48: runtime error: signed integer overflow: 838860800 * 4 cannot be represented in type 'int'
+SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior src/mat4.c:323:48 in
+```
+ 
+Cast the offending `rows` and `cols` ints to `sf_count_t` (the type of
+`dataend` before performing the calculation, to avoid the issue.
