The crash is expected. It's mentioned in their FAQ's that is Valgrind
reports invalid reads or writes, there is a large chance that valgrind
itself will crash in m_memcheck. So, unless Valgrind continues to crash
after the errors are fixed, this is expected behaviour.

I am not really sure as to what causes this to come up and why it must be
suppressed. I'll dig deeper when I have the time.
