I think this is https://bugs.llvm.org/show_bug.cgi?id=46176
It looks like the build is 32-bit, judging by the width of the hex pointers in
the stack trace. Debug is the default CMake config, so that's probably in play
too.
It's an MSVC bug:
https://developercommunity.visualstudio.com/content/problem/1179643/msvc-copies-overaligned-non-trivially-copyable-par.html
MSVC passes SmallVector by value incorrectly in this config. ¯\_(ツ)_/¯
We landed a workaround, but I don't think it's in LLVM 10:
