This is too bad! In my experience most seismological centers are running
Ubuntu world-wide. This is especially true in Central America where there
is strong interest in partnering up Ubuntu-based SeisComP installs with
ShakeMap.

Here is what I see (it looks like grdmath is terminated prematurely):

I tried Googling "grdmath buffer overflow detected" but only came up with
this:
https://geohazards.usgs.gov/pipermail/shake-dev/2011-October/000380.html

I then tried running with no xml flag as suggested. The errors are the
same.

Nope, they look like they were all eliminated:
osop at osop-displays2:/opt/shakemap/data/9583161/output$ ls
bias.txt  grid.xml  grid.xyz  info.xml  pga.grd  pgv.grd  rock_grid.xml
 stationlist.xml  uncertainty.xml  urat_pga.grd
