>From etc/DEBUG:

    ** When you are trying to analyze failed assertions, it will be
    essential to compile Emacs either completely without optimizations
    or at least (when using GCC) with the -fno-crossjumping option.
    Failure to do so may make the compiler recycle the same abort call
    for all assertions in a given function, rendering the stack
    backtrace useless for identifying the specific failed assertion.
