- Apply this upstream fix as a patch: https://github.com/llvm/llvm-
+ * opt-viewer renders its HTML using several parallel worker processes,
+ and they all share a helper process (c++filt) that demangles function
+ names. The lock that protects the helper was only created at the same
+ time as the helper, on first use. A worker could reach demangle() before
+ the lock existed, crashing. The fix is to ensure that the lock always
+ exists and hold it when the helper is created.
