I committed my patch, r266436, using the current format for .covmapping file, and then buildbots complained about it: * http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fast/builds/11935/steps/check-llvm%20ubsan/logs/stdio * http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-bootstrap/builds/11460/steps/check-llvm%20ubsan/logs/stdio I tried to reproduce the issue locally, but didn't succeed.

Hi!

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 woul...
