Comment 18 for bug 1538361

I have tested the remaining 14 files. They all behave the same as before, nothing has changed.
- wrt the options -g -O0, these options were rejected by btool, so I did a normal compile
- wrt the issue of text, as far as I can tell, all the files are missing all the text.
- attached is a complete backtrace obtained from the file Shape Graph.emf
