[LLVMdev] UBSan detects misaligned memory accesses in llvm-profdata and llvm-cov
...tp://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-bootstrap/builds/4526/steps/check-llvm%20ubsan/logs/stdio
Also see http://llvm.org/bugs/show_bug.cgi?id=20815.
The error reports look vaild: in general it's incorrect to load uint64_t,
or even structures like "RawHeader" or "CoverageMappingTURecord" from a
random address. Also, if you parse files stored on disk, it would certainly
help to know endianness of data in these files and, e.g., use routines from
Support/Endian.h. Can you take a look at this?
