FYI, just bisected out and found this commit starts to get the segfault:

    preproc: defer %00, %? and %?? expansion for nested macros, cleanups

    BR 3392603: When doing nested macro definitions, we need %00, %? and
    %?? expansion to be deferred to actual expansion time, just as the
    other parameters.

    Do major cleanups to the mmacro expansion code.
