The same as below happens on xulrunner nightlies. This affects current aurora and m-c. (We really should make it die for good... or at the very least unhide the jobs on tbpl/treeherder, because we usually don't notice until it's too late and we don't have SDKs anymore ; this time we're lucky) +++ This bug was initially created as a clone of Bug #1054738 +++ When building TB on MacOSX 10.8 opt get the following: Executing: /usr/local/bin/ccache ../../../../../clang/bin/clang++ -arch i386 -Qunused-arguments -Qunused-arguments -Wall -Wpointer-arith -Woverloaded-virtual -Werror=return-type -Werror=int-to-pointer-cast -Werror=type-limits -Wempty-body -Wsign-compare -Wno-invalid-offsetof -Wno-c++0x-extensions -Wno-extended-offsetof -Wno-unknown-warning-option -Wno-return-type-c-linkage -isysroot /Developer/SDKs/MacOSX10.7.sdk -fno-exceptions -fno-strict-aliasing -fno-rtti -ffunction-sections -fdata-sections -fno-exceptions -fno-math-errno -std=gnu++0x -pthread -DNO_X11 -pipe -DNDEBUG -DTRIMMED -g -O3 -fno-omit-frame-pointer -fPIC -o XUL -Wl,-filelist,/builds/slave/tb-c-cen-osx64-000000000000000/build/objdir-tb/i386/mozilla/toolkit/library/tmp2Dr0ES.list -framework Cocoa -lobjc -framework AudioToolbox -framework ExceptionHandling -Wl,-executable_path,/builds/slave/tb-c-cen-osx64-000000000000000/build/objdir-tb/i386/mozilla/dist/bin -Wl,-dead_strip ../../js/src/libjs_static.a ../../js/src/libjs_static.a ../../xpcom/typelib/xpt/libxpt.a ../../intl/unicharutil/util/internal/libintl_unicharutil_util_internal.a ../../security/nss/lib/crmf/libcrmf.a ../../js/src/libjs_static.a ../../intl/icu/target/lib/libicui18n.a ../../intl/icu/target/lib/libicuuc.a ../../intl/icu/target/lib/libicudata.a ../../config/external/nss/libnss3.dylib ../../ldap/sdks/c-sdk/ldap/libraries/libldap/libldap60.dylib ../../ldap/sdks/c-sdk/ldap/libraries/libldif/libldif60.dylib ../../ldap/sdks/c-sdk/ldap/libraries/libprldap/libprldap60.dylib ../../memory/mozalloc/libmozalloc.dylib -dynamiclib -install_name @executable_path/XUL -compatibility_version 1 -current_version 1 -single_module -L/builds/slave/tb-c-cen-osx64-000000000000000/build/objdir-tb/i386/mozilla/dist/lib -lmozglue -lm -Wl,-framework,CoreLocation -Wl,-framework,QuartzCore -Wl,-framework,Carbon -Wl,-framework,CoreAudio -Wl,-framework,AudioToolbox -Wl,-framework,AudioUnit -Wl,-framework,AddressBook -Wl,-framework,OpenGL -framework Cocoa -framework AudioToolbox -framework OpenGL -framework SystemConfiguration -framework QTKit -framework IOKit -F/System/Library/PrivateFrameworks -framework CoreUI -lcups /builds/slave/tb-c-cen-osx64-000000000000000/build/objdir-tb/i386/mozilla/toolkit/library/tmp2Dr0ES.list: StaticXULComponentsStart.o . . . ld: bad codegen, pointer diff in __ZN21XPCWrappedNativeScopeC2EP9JSContextN2JS6HandleIP8JSObjectEE to global weak symbol __ZTVN2JS10WeakMapPtrIP8JSObjectS2_EE for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) make[7]: *** [XUL] Error 1 make[6]: *** [toolkit/library/target] Error 2 Works fine for MacOSX 10.8 debug

It's actually beyond critical, since the SDK is a release deliverable, and this bustage is on beta, which builds releases. Builds one pretty darn soon, too. [Tracking Requested - why for this release]: Drivers: just housekeeping moving the flag here, you already plussed it for 34 in bug 1060995, but it wound up with an independently-noticed fix here instead.

per lmandel on IRC, we will not rebuild 34.0b1 to pick up this fix, but would like it for 34.0b2 early next week.

(In reply to Nick Thomas [:nthomas] from comment #6) > per lmandel on IRC, we will not rebuild 34.0b1 to pick up this fix, but > would like it for 34.0b2 early next week. Correct. Please commit Thursday or Friday this week so that we're set for beta2.
