It has 2 of them:
apps/s_cb.c:1077:41: runtime error: index 18446744073709551614 out of bounds for type 'const unsigned char [3]'


I've already fixed this, it's been reviewed, it's just not in
master yet.

Then there is also:
crypto/include/internal/md32_common.h:380:5: runtime error: store to misaligned address 0x00000210b5fd for type 'unsigned int', which requires 4 byte alignment

That seems to go away when using -DPEDANTIC
