Hi everyone, I'm Edward-san, a contributor developer of cppcheck (link: http://cppcheck.sourceforge.net/ ) and I noticed a strange thing when I was compiling it with some particular flags. It happens with gcc 4.5.2 (the supplied one from Linux Mint 11 packages), gcc 4.6.3 (the one which came out from Ubuntu 12.04) and in gcc 4.7.1 (compiled by myself). To reproduce the problem, download the source here: https://github.com/danmar/cppcheck/zipball/master and unzip it somewhere. In the new folder, write in the terminal: "make lib/errorlogger.o 'CXXFLAGS=-Winline -O' " g++ will output these messages: g++ -Winline -O -Ilib -c -o lib/errorlogger.o lib/errorlogger.cpp lib/errorlogger.h: In member function ‘void ErrorLogger::reportUnmatchedSuppressions(const std::list<Suppressions::SuppressionEntry>&)’: lib/errorlogger.h:147:36: warning: inlining failed in call to ‘ErrorLogger::ErrorMessage::~ErrorMessage()’: call is unlikely and code size would grow lib/errorlogger.cpp:342:143: warning: called from here but in lib/errorlogger.cpp/h there's no declaration of the ErrorLogger::ErrorMessage destructor. If you compile the program with that options, ie: "make 'CXXFLAGS=-Winline -O' " you'll get It isn't possible to reproduce this without '-O'. Maybe I don't know something about this... if it's not a false positive, what would it be the way to fix this? Do you need the preprocessed source? g++ -v output: Using built-in specs.
