Seems to affect 17ESR line only, 21.0 is completely built with no-strict-aliasing. Looks like we miss that on some places on ESR 17. hm, I wonder why the same code built on Fedora 18 (gcc version 4.7.2 20121109 (Red Hat 4.7.2-8) (GCC)) does not produce the warnings: c++ -o jscrashreport.o -c -I./../../dist/system_wrappers_js -include /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/config/gcc_hidden.h -DENABLE_YARR_JIT=1 -DMOZ_GLUE_IN_PROGRAM -DEXPORT_JS_API -DJS_HAS_CTYPES -DDLL_PREFIX=\"lib\" -DDLL_SUFFIX=\".so\" -DNO_NSPR_10_SUPPORT -DUSE_ZLIB -Ictypes/libffi/include -I. -I/home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/../../mfbt/double-conversion -I/home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src -I. -I./../../dist/include -I/usr/include/nspr4 -I/home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src -I/home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/assembler -I/home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/yarr -fPIC -pedantic -Wall -Wpointer-arith -Woverloaded-virtual -Werror=return-type -Wtype-limits -Wempty-body -Wno-ctor-dtor-privacy -Wno-overlength-strings -Wno-invalid-offsetof -Wno-variadic-macros -Wcast-align -Wno-long-long -O2 -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fpermissive -gdwarf-2 -fno-rtti -ffunction-sections -fdata-sections -fno-exceptions -pthread -pipe -DNDEBUG -DTRIMMED -g -O3 -freorder-blocks -fomit-frame-pointer -DUSE_SYSTEM_MALLOC=1 -DENABLE_ASSEMBLER=1 -DENABLE_JIT=1 -DMOZILLA_CLIENT -include ./js-confdefs.h -MD -MF .deps/jscrashreport.o.pp /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jscrashreport.cpp jsinfer.cpp In file included from /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jsapi.h:26:0, from /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jscrashreport.cpp:8: /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/gc/Root.h: In static member function 'static void JS::RootSink<JSStableString*>::dispose(JSStableString*)': /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/gc/Root.h:279:35: warning: variable 'sink' set but not used [-Wunused-but-set-variable] In file included from /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jsapi.h:32:0, from /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jscrashreport.cpp:8: ./../../dist/include/js/Vector.h: At global scope: ./../../dist/include/js/Vector.h:572:1: warning: function 'bool js::Vector<T, MinInlineCapacity, AllocPolicy>::calculateNewCapacity(size_t, size_t, size_t&)' redeclared as inline [-Wattributes] In file included from /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jsapi.h:32:0, from /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jscrashreport.cpp:8: ./../../dist/include/js/Vector.h:191:36: warning: previous declaration of 'bool js::Vector<T, MinInlineCapacity, AllocPolicy>::calculateNewCapacity(size_t, size_t, size_t&)' with attribute noinline [-Wattributes] In file included from /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jspropertycache.h:15:0, from /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jscntxt.h:23, from /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/jscrashreport.cpp:9: /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/vm/String.h:398:24: warning: inline function 'static void JSString::writeBarrierPost(JSString*, void*)' used but never defined [enabled by default] /home/komat/CVSRH/xulrunner/rhel-6.5/xulrunner-17.0.6/mozilla-esr17/js/src/vm/String.h:397:24: warning: inline function 'static void JSString::writeBarrierPre(JSString*)' used but never defined [enabled by default] An upstream bug - https://bugzilla.mozilla.org/show_bug.cgi?id=821502 The fix has been uploaded to git and will be released with next Firefox update.
