Created attachment 348582 [details, diff]
sizeof-pointer-warn.patch

This warning is new in gcc 4.8 and is serious enough for a qawarn.

Alternatively since all warnings since 4.6 append the flag name we could just grep for ": warning: .*\[-Wsizeof-pointer-memaccess\]" and not worry about the string changing in the future.

Thanks, this is in git:

I used the .*\[-Wsizeof-pointer-memaccess\] expression as you suggested.

This is fixed in 2.1.12.1 and 2.2.0_alpha176.
