Hi,
I have an update to the test results for libc++. Clang can now correctly handle exceptions if the GCC it uses the libgcc from is compiled for dw2 exceptions, which only works on 32-bit Windows.
So all the false negatives should be filtered out currently, leaving the real issues. I have attached a patch to the results.windows.html web page detailing the changes.
Current tally is:
6.7% test failures, 9.7% sections with failures.
IIRC, last time this was around 13% test failures. Note I haven’t changed anything since that run 
Please apply when you find the time!
Thanks!
Ruben
