I tried to use -Weverything on a C++ project with about 350 source

useful.

Hi Everyone,
We are tracking an issue on ppc64-le and GCC 8. We can duplicate it on
GCC112 when using /opt/cfarm/gcc8-r257824 compiler. Also see
https://github.com/weidai11/cryptopp/issues/588.
We have the issue isolated, but its not really reduced yet. When '-O2
-fstack-protector-strong' is used

Hi All,
How do I add a sequence point in my C/C++ code?
Googling brings up a lot of 'volatile' hits, but I believe that's an
abuse of GCC's interpretation of volatile since I'm not working with
memory mapped hardware or registers.

Hi All,

Is there an option to initialize variables to known values in a C/C++ program?
My use case is 'debug' builds and finding use of uninitialized values
that get lucky by being 0 most of the time. For example:

Hi All,
I'm working on Apple, so I'm stuck with some ancient stuff. I'm trying
to compile with -Wall -Wextra -Wconversion, and I'm catching a warning
similar to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38116.
The 38116 bug defers to Bug 6144
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=6614).
