What warnings do you get?
I haven't tried compiling WebCore and WebKit with -fstrict-aliasing.
However, I suspect that the warnings and errors you get result from
type punning through pointers. To make the code safe for strict
aliasing, you would need to change all pointer-based type punning to
union-based type punning.
I think there's a compiler warning flag, like -Wstrict-aliasing, that
can help you track down unsafe type punning.
