Perhaps you can just force it off. Does
#pragma GCC optimize ("no-strict-aliasing")
do what you want? and/or
__attribute__ ((optimize("no-strict-aliasing")))
on particular functions?
I haven't tested this, but
http://gcc.gnu.org/onlinedocs/gcc-4.4.2/gcc/Function-Specific-Option-Pragmas.html#Function-Specific-Option-Pragmas
http://gcc.gnu.org/onlinedocs/gcc-4.4.2/gcc/Function-Attributes.html
implies it might work.
