David, Dean, all,
The bots got red today with assertion failures in llvm::DbgVariable::addMMIEntry:
I did not find the offender yet. Any ideas?
I give it 99% odds it was r302483. Let’s revert and debug it tomorrow.
I take it back, that build doesn’t have that revision. It could be r302461, which is from the first failing build: http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/1815
That revision is much safer, though. I am rebuilding with debug info enabled. First I ran check-msan without RelWithDebInfo, and of course I didn’t reproduce the problem.
This wasn’t either of my changes, it was actually Adrian’s r302469, which Hans reverted this morning. See http://llvm.org/PR32977
Thanks again! The bots are delighted
