Ever since I updated from -r325700 to -r325997 I've been having odd, non-repeatable, fairly rare problems on amd64. (I've yet to see if I get similar issues on other platforms.)
I've reported a couple of panic for page faults in kernel mode in other list messages. But I'm also getting things like clang failing assertions that do not repeat when the compile is simply retried with the same input files. I only mention locking because of recent head/sys/kern activity between -r325700 and -r325997, the intermittent nature of the observed failures, and the wide variety of contexts (kernel, world). I do not have specific evidence of a specific cause. (I do not see how I'm ever going to get any such evidence.) The following error did not repeat on a simple retry of the compile: --- Sema/SemaDeclAttr.o --- Assertion failed: (I->second && I->first == I->second->getValPtr() && "List invariant broken!"), function AddToUseList, file /usr/src/contrib/llvm/lib/IR/Value.cpp, line 793. c++: error: unable to execute command: Abort trap (core dumped) c++: error: clang frontend command failed due to signal (use -v to see invocation) FreeBSD clang version 5.0.0 (tags/RELEASE_500/final 312559) (based on LLVM 5.0.0svn) Target: powerpc-unknown-freebsd12.0 Thread model: posix InstalledDir: /usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/powerpc.powerpc/tmp/usr/bin c++: note: diagnostic msg: PLEASE submit a bug report to https://bugs.freebsd.org/submit/ and include the crash backtrace, preprocessed source, and associated run script.
