I was able to build with LTO (-O4) on OS X nicely, till Gecko 13. Since Gecko 14 it now fails with the following error at the end of the build:

ld: warning: ignoring file /Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks//QuickTime.framework/QuickTime, file was built for unsupported file format ( 0xce 0xfa 0xed 0xfe 0x 7 0x 0 0x 0 0x 0 0x 3 0x 0 0x 0 0x 0 0x 9 0x 0 0x 0 0x 0 ) which is not the architecture being linked (x86_64): /Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks//QuickTime.framework/QuickTime

This is true for Apples Clang 3.1 on OS X 10.4.7 and with Apples Clang 4.0 on OS X 10.8. It builds nicely with -O3 instead of -O4. I build with CXXFLAGS="-O4" CFLAGS="-O4" LDFLAGS="-O4".

This works again for me since Gecko 17. :-)
