So that change is basically allowing trinity to munmap just part of a prior mmap.
So it may do things like..

mmap |--------------|

munmap |----XXX-------|

munmap |------XXX-----|

ie, it might try unmapping some pages more than once, and may even overlap prior munmaps.

until yesterdays change, it would only munmap the entire mmap.

There's no easy way to tell exactly what happened without a trinity log of course.

I've attached the trinity log of the child that triggered the bug. Odd thing is that I
don't see any munmaps in it.

Thanks,
Sasha
