I can't reproduce on Ubuntu 14.04, but I can on a CentOS 7.2 x86_64
box here at work.

I'm not sure I'm doing what Eric has asked. I've never used gdb before
and it took me a while to figure out what scons was doing during scons
check. I chose the tn200 test as one of the many that are giving the
error.

Then output goes on forever, presumably consuming gpsfake data.

Here's a sample of scons check output, snipped down.
