Hi Stefan,
Yes, I've added -fno-strict-aliasing to the 'Other C++ Flags' setting in
Xcode but it seems to be ignored, even though it does appear in the command
line. One thing that might matter is that it is added after all other
options. Here is part of the command line:
/usr/bin/gcc-4.0 -x c++ -arch
ppc -pipe -Wno-trigraphs -fpascal-strings -faltivec -fasm-blocks -O3 -Wreturn-type
-Wformat -Wmissing-braces -Wparentheses -Wunused-function -Wunused-label -Wunused-variable
-Wunused-value -Wsign-compare -DMACOSX -DAUDIOUNITS -fmessage-length=0 -funroll-loops
-ffast-math -mtune=G4 -ftree-vectorize -fvisibility-inlines-hidden -Wno-invalid-offsetof
-mmacosx-version-min=10.3
<includes skipped>
-DNDEBUG -fno-strict-aliasing -falign-loops=16 -isysroot
/Developer/SDKs/MacOSX10.3.9.sdk -include
/Library/Caches/com.apple.Xcode.501/SharedPrecompiledHeaders/pch-fjwtzxtrfzovnrcfiacmnnqisrwj/pch.h
<paths skipped>
Best regards,
Frederik Slijkerman

Please, please, can someone tell me how I can turn off strict aliasing

still being able to compile at the -O3 level? Thanks!
Did you try -O3 -fno-strict-aliasing?
