flex.c grows uncontrollably

[clasqm]

OK,  I did the following

• moved yab_work back to ~ and symlinked that to my Programming folder instead of the other way round
  
• deleted the Buildfactory folder
  
• emptied the Trash
  
•  uninstalled BuildFactory
  
• reinstalled it
  

and ...

Code:

At this stage there is a freeze and CTRL-C is needed to continue

Code:

So the flex.c problem has gone but there is something else wrong.
