In fact it is not adding but rather deleting (filtering out) -fno-strict-aliasing flag. There is no explanation but it works :) . I use gcc 3.4.1 with CFLAGS="-O2 -fPIC -mtune=powerpc -fno-strict-aliasing -pipe -Wl,-z,now".
The problen is fixed after -fno-strict-aliasing flag has been filtred out.
I agree that it could be a compiler bug.

That bug report is pretty vague.  It's not clear to me that this is
due to a buffer overflow problem.  It could just be a compiler bug,
for example.  Or it could be something else.  I don't offhand see why
adding -fno-strict-aliasing would fix a buffer overflow problem.
