Package: g++-4.4 Version: 4.4.2-5 Severity: normal
Consider following code: ---------- test.cpp --------- #include <arpa/inet.h> void test() { uint16_t s = 123; // No warning expected here uint16_t swapped = htons( s ); } ------------------------------ g++-4.4 -Wconversion -Werror -c test.cpp => no error g++-4.4 -O2 -Wconversion -Werror -c test.cpp => error! (this also applies to g++-4.3, not 4.2) I don't see why the optimization changes the triggering of the warning, this is very painful because it requires either disabling -Wconversion or -Werror, which are not acceptable for high quality code.
