Hi,
many times we copy code snippets from sources that change the
Unicode quotation marks ( “ ” ) rather than " ". For example
const std::string a_string(“Hello”);
That line looks innocent but causes gcc to say
x.cpp:4:1: error: stray ‘\342’ in program
const std::string a_string

This is derived from https://gcc.gnu.org/ml/gcc-help/2015-03/msg00091.html
Currently, gcc provides an optimization that transforms a call to
malloc and a call to memset into a call to calloc.
This is fine except when it takes place within the calloc() function
implementation itself, causing a recu
Hi,
the particular motivation is a TMP compile-time search of an
element, but could be extended to other scenarios.
In my example, given:
template
struct Static_Find
{
static size_t find(size_t /*target*/)
{
return 0;
}
};
template
struct Static_Find
{
static size_t

Hi,
I have a large codebase where at some point, there's a structure
that takes an unsigned integer template argument, and uses as the size
of an array, something like
template
struct Struct
{
typedef std::array Chunk;
typedef std::list Content;
Content c;
};
Changing the values
Hi falks,
since the last WG21 meeting held at Rapperswil, where I gave a

I'm pursuing the creation of a Committee's Working Group.
There was agreement that the issues were relevant a
Hi,
should gcc warn at least if a dynamic_cast of a reference is used when
-fno-exceptions is specified?
At least 4.8.2 doesn't complain.
If so, I can implement the fix.
Example:
struct Base
{
virtual void f(){}
};
struct Der : Base {};
int main()
{
Der d;
Base& b = d;

If the STL is compiled with exceptions support, I can't get rid
off its overhead. It's not just about not using
Hi,
I am needing a truly exceptions-clean (or exceptions-free) binary due to
some embedding systems platform.
-fno-exceptions is not enough of course.
I am thinking about taking the concept to the backend through multilibs:
add some general -mno-exceptions or alike so there can be a selectable

Hi,
assuming the need to generate code in which
almost everything is used 3x (e.g. 3x registers,
3 times data, etc.) for a specific purpose (*) for any
given target,
what would be the best way to implement it?
(let's name this 3ple-voting behavior)
a) as a forked backend target of each target

Hi,
is there any plan to release a gcc 4.8.3?
Thanks,

Please let me know if this is truly a bug, in which case I could also
fix it for the latest version as well
(if so, please let me know if I should look into trunk or any other branch).
Thanks,

Hi,
assigning a negative literal to an unsigned variable issues no warning:
unsigned int x;
x =- 4;
This is specially important in typos when -= was intended instead of =-
Would be acceptable if I add a new warning to handle this, i.e.
-Wnegative-to-unsigned
or alike?
Thanks,
