There was a report that the same problem happened with the unicode-2
Emacs branch.  That seems to have been spurious.  But as far as I know
that doesn't mean your problem isn't real.

Can you please try building the previous pretests, and see if
the problem has appeared recently?


    to this line

    LC_ALL=C $(RUN_TEMACS) -nl -batch -l loadup dump

    works, although there are some conflicting reports about this, also.

It is possible that this is a Glibc bug, perhaps due to some
private change in Fedora's version of Glibc.

Here is an idea.  You could try changing emacs_blocked_malloc
so that, when Vpurify_flag is non-nil, it uses mallopt to prevent
malloc mmap'ing.  It could save the value of the N_MMAP_MAX
parameter, then set it to 0, then call malloc, then restore
the old value of the parameter.  But it should do this
only when Vpurify_flag is non-nil.

Does that fix the problem?
