Some developers know boost::polygon has an issue when compiled with g++
4.7.2 (currently the lasted version on MinGW) using the -O2 (or more)
optimization level.
I am not 100% sure, however I am guessing this issue was also reported
on Linux.
The developer of boost::polygon asked me to test (if possible) this
issue with g++ 4.7.3 (He has some trouble to reproduce it)
I did not found this version for MinGW, and I am reluctant to install
this version on my Linux Ubuntu 10 LTS 32 bits (because I found the C
compiler v 4.7.3, but not the C++ compiler).
Currently I have a 4.6 version which does not create this issue.
So I am searching for developers who have G++ 4.7.3 (and/or a more
recent version) on their machine to compile and test this program.
See
https://svn.boost.org/trac/boost/ticket/7983
for the test program and more info
Thanks for your help
