<pre>Originally reported at <a href="https://github.com/google/sanitizers/issues/622">https://github.com/google/sanitizers/issues/622</a>
Building with
-fsanitize-undefined-trap-on-error -ftrap-function=abort
all checks inside one functions are jumping to a single abort() call. This way
it's impossible to tell which one has failed, and there may be dozens of checks
in larger functions.
We should consider doing something similar to what ASan does to ensure that
calls to __asan_report_* are not merged.</pre>
