Exact steps for others to reproduce the error
I only need to sculpt for a few minutes to produce the error, but I'm not sure exactly what sculpt feature triggers it.

Took a while to reproduce this, but I can confirm this (happened in DynTopo for me)

The BMLogEntry->deleted_verts->entrypool is NULL, thus the crash in BLI_ghash_free()

Will have a look later why this happens... Seems to be related to undo refactor, so @ideasman42 might know right away?

@lichtwerk @ideasman42 forgive my bump, but this sculpt crash is the only issue holding me back from using the daily builds, and currently I have to use the daily builds (due to different issue in .79b stable).

@ideasman42 : assigning to you since this happens in UNDO...

There have just been two fixes regarding sculpt/dyntopo (5330f1c5d1, 6242940639)
With these changes I cant reproduce this anymore (thanx @Campbell Barton (campbellbarton)! )

So @JonathanDunlap: could you check master build from https://builder.blender.org/download? (pretty sure this should be resolved there) and please report back if this indeed fixes it for you...

Marking as incomplete for the time being...

@lichtwerk I've checked out the master builds and gave it a spin for about 10 minutes (needed to head out to work soon). So far, I experienced no crashes! Normally I'd crash within 3-4 minutes of sculpting, so this this looking pretty positive.

Glad to hear! Think we can close this then... (feel free to report back if something creepy comes up again)
