[cfe-dev] -fsanitize=undefined and shared libraries

[zapadinsky]

I have had a similar problem with integer checks. compiler-rt was not linked
to .so files and there were unknown references to
__ubsan_handle_add_overflow and so on.

I managed this issue adding "-Wl,--whole-archive
-L/usr/local/lib/clang/3.3/lib/linux/ -lclang_rt.ubsan-i386
-Wl,--no-whole-archive" to command line... and its not a beautiful solution.

When this issue will be fixed in trunk?
