This is indeed some strange behavior.
In script mode, the following works:
f = Import("/usr/lpp/dx/samples/data/wind.dx");
but this gives a Bus Error:
f = Import("/usr/lpp/dx/samples/data/wind");
But it gets weirder:
If you debug dxexec in script mode I get the following:

However, if you debug in VPE mode (just the Import) you get:

And to top it off, if you change the Import to include the ".dx" extension, it
works.
