[Magic-dev] Extraction error

[Bertrand Irissou]

 Hi Tim,

 I think I have uncovered a pretty serious extraction error.
 If you extract the file bug.mag, you will see that the bug.ext file 
merges the nodes "n1" and "gnd". This is clearly a bug since the ptub 
and ntub are not connected.
 I have narrowed it down to the fact that the ntub has a 45 degree 
angle. If the tub has 90 degree angles it work fine, but as long as a 
single one is present, it extract incorrectly.

 Sincerely,

 Bertrand.
