     Type:  Bugs                   |      Status:  new     
Milestone:  To Be Determined       |   Component:  polygon 
  Version:  Boost 1.53.0           |    Severity:  Problem 
 Keywords:                         |  
-----------------------------------+----------------------------------------
 Difference (and Sum) of 2 polygons ( a main polygon, and a small polygon
 inside the main polygon) creates a void or erroneous polygon when compiled
 with gcc 4.7 and -O2 optimization, and the same code works fine when using
 -01 optimization, or when using a GCC version older than 4.7 (with any
 optimization level)
 (Tested on Mingw and Linux)
 ( This issue is also found in 1.49 and other boost versions I have used).
