Windows 10. I saw something curious and wondered if any of the ninja or<br>
CMake experts out there can explain/fix it.<br>

Creating library lib\LTO.dll and object lib\LTO.exp<br>
[3120/3121] Running the LLVM regression tests<br>
[[[ etc ]]]<br>
<br>
I'm curious about the "creating library" message popping out twice.<br>
Sometimes ninja builds will die on me, complaining about a corrupted<br>
object file, usually related to LTO. Rerunning ninja usually completes<br>
successfully. So I wonder if there's some mishap in the dependencies<br>
somewhere that actually causes the build to try to link the DLL twice,<br>
which of course might corrupt a file if the links are overlapping in<br>
time.<br>
<br>
Thought I'd throw this out there in case someone wants to take a look.<br>
