* [Bug c++/29219] New: Template instantiation problem - Different behavior between gcc 4.0.x and gcc 3.4.x. @ 2006-09-25 20:15 etienne dot clement at autodesk dot com 2006-09-25 20:19 ` [Bug c++/29219] " etienne dot clement at autodesk dot com 2006-09-25 21:11 ` pinskia at gcc dot gnu dot org 0 siblings, 2 replies; 3+ messages in thread From: etienne dot clement at autodesk dot com @ 2006-09-25 20:15 UTC (permalink / raw) To: gcc-bugs If you compile the attached code using g++ 4.0.x using the following command: > g++ -v -save-temps -O3 -c bug.cpp and look at the list of symbols in the bug.o file using the following command: > nm bug.o You will see that g++ generates a symbol for 'PxlMonoLimit<(PxlFormat)0>::limit'. IMHO, there is no reason to generate such a symbol. g++ 3.4.x do not generate one.
