I ran a few test compiles, and from what I can see the map has func_detailed displacements, note that displacements cannot be turned into brush entities and that doing so causes the compile to fail entirely.
For some reason on the first compile I did I got a ***leaked*** error as well, however the pointfile pointed straight through a solid brush and hiding the entity it was coming from fixed the problem, so i'm not too sure what is going on there, it could have been a side effect of the error described above.
