I tried this code, which came from a modified version of the
numintsynth.pyscript of @raphlinus'spiroproject:https://gist.github.com/ctrlcctrlv/4007872ebc7bdac4f6c3e33051bef8d9
Don't be discouraged by the fact it is ≈5000 lines, it comes from a Python script, to wit:
https://gist.github.com/ctrlcctrlv/bdcab4072a5862ef7c4e9f2a779bdbb4
I expected to see this happen: a successful compilation
Instead, this happened:
rustccrashed.Meta

This might be a bug in llvm. The crash seems to blame the function https://llvm.org/doxygen/DwarfCompileUnit_8cpp_source.html#l01051 ```DIE *DwarfCompileUnit::createAndAddScopeChildren(LexicalScope *Scope, DIE &ScopeDIE)``` ultimately.
