I have been unable so far to make a test program to demonstrate this problem
that we experience in a real app. The problem does not arise unless some
additional arenas are created, something that I have not yet figured out how to
make happen on purpose. Perhaps another way of looking at the problem is that
there may be a spurious failure of mmap, which seems to be the only way I can
see for additional arenas to be made, at least as configured in FC4. Still, I
claim the bug is real and my patch corrects for it if/when such a spurious
failure occurs.
By the way, the code in question is essentially unchanged in glibc 2.4, but I'm
not running that, so I made the report vs. 2.3.6.
