This is moving one of the items discussed in the 1.39.0 thread to its own topic. >From 1.38.46-upstream when linking our largish library we get the following error produced and this still happens with 1.39.2:-

I guess it started when this code for __threwValue was merged into libcompiler_rt instead of being in its own file?
