This seems to indicate that either you have not built this part of Xt 
with "-g" or something in your build process has stripped this info off.

Please take out the '0'. I'm not sure what level 0 actually means but
smaller numbers usually include less debugging information. 2 is the
default. I'd suggest you leave it there and just do '-g'.
