A class with virtual functions with no definition
clang 3.4 / 3.5, gcc 4.7 / 4.9, and sun studio (12.3 & 12.4) compile and link
the example fine; this is only an issue when using sanitizers. When built with
-fsanitize=undefined using gcc 4.9.0, it also compiles/links fine.
When the 'virtual' keyword is removed from the example code it fails to link
with or without the sanitizer.
The error received:
/tmp/main-c376a0.o:(.data+0x48): undefined reference to 'typeinfo for Blah'
clang: error: linker command failed with exit code 1 (use -v to see invocation)</pre>
