I think the reset should be outside the #ifdef. Couldn't the app install an
"ignore" malfunction handler and fall through? If so, we want the statement
reset.

SVN_ERR_MALFUNCTION_NO_RETURN() can't return (as the name implies).
Therefore the compiler will warn that the following code is unreachable.

No. SVN_ERR_MALFUNCTION_NO_RETURN() doesn't return. (It abort()s if
the handler returns)
