I have just tested here using William's 6.3 binaries from a few weeks
ago and I too get a Bus error when trying to start d.measure. (Minimac
+ OSX 10.4)

gdb is not installed on the lab Macs and I'm not sure how to set things
to have it produce a core dump to the terminal upon errors.

g.gisenv set="DEBUG=5"  doesn't give any additional output.

one thing I forgot to try was a simple 'd.measure --help'
