crash dump

For smaller programs -fsanitize-coverage=trace-pc works very well with clang
targeting the MSVC ABI on Windows. Unfortunately more complex programs ICEs the
compiler:

C:\Users\ned\Documents\boostish\kerneltest\test>clang++ -shared -fexceptions -o
test_output.dll coverage_main.cpp -I.. -DUNICODE -fsanitize-coverage=trace-pc
