I can't reproduce and looking at the code, I don't see how this would happen. Are you sure you aren't building with clang w/ libunwind as unwinder lib?
Here's info about the system. I'll try to emerge libunwind and clang again, but I haven't switched USE flags or changed anything from what's below. Although for compiler-rt I compile it without thinlto because it doesn't compile with thinlto.
