Hello, gcc version 4.7.3 (Ubuntu/Linaro 4.7.3-1ubuntu1)
g++ -Wall -O2 -I /g/boost_1_53_0 test_polygon_diff.cpp ./polyset polygons count 1 polygon 0, corners count 12 // polyset polygons count 1 **** polygon 0, corners count 12 10, 10 5, 10 5, 5 5, -5 -5, -5 -5, 5 5, 5 5, 10 -10, 10 -10, -10 10, -10 10, 10 Same results for O1, O3 Milan Dne 17.6.2013 10:15, jp charras napsal(a):
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
