[Bug c/61502] == comparison on one-past pointer gives wrong result
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61502
--- Comment #4 from Harald van Dijk harald at gigawatt dot nl ---
That's an interesting argument. You may well be right that the original code,
strictly speaking, does not prove that GCC has a bug, but I do think GCC has a
bug nonetheless, and have come up with a different example.
#include stdio.h
#include string.h
int x, y;
char buf[sizeof (int *)];
int main()
{
int *p = y;
memcpy (buf, p, sizeof p);
memcpy (p, buf, sizeof p);
x = 2, y = 1;
if (p == x + 1)
*p = 2;
else
y = 2;
printf (x = %d, y = %d\n, x, y);
return 0;
}
Compiling with -O2, I see x = 2, y = 1. p has been assigned y. Whether it
compares equal to x + 1 is unspecified, but it doesn't change its origins: p
points to y. Therefore, either the assignment to *p should change y, or in the
else branch, the plain assignment to y should change y. Either way, the correct
result is x = 2, y = 2.
It seems like GCC is assuming that if p == x + 1, and x + 1 != y, then p !=
y, so the assignment to *p cannot change y. The flaw in that logic is again
the optimisation of x + 1 != y to a constant.
I see the behaviour I describe in versions 4.9.0 and 4.8.2. This program does
print x = 2, y = 2 in my testing on GCC 4.7.3, but that is because p == x +
1 happens to not compare as true in that version. Slightly tweaked versions of
this fail with versions 4.7.3, 4.6.4, 4.5.4 and 4.4.7, but not 4.3.6.

Created attachment 32936
-- https://gcc.gnu.org/bugzilla/attachment.cgi?id=32936action=edit
this patch works for me
the main problem seems to be, that
@item is not working inside @cartouche
so I moved all @items up by 3 lines.
then the System.Task_Info (s-tasinf.ads) needs to be
in the menu.
While editing, I saw the following:
initially there were two paragraphs *53*
one about The semantics of operations on invalid representations.
and one about The manner of choosing a storage pool for an access type
And the latter was referenced from two other paragraphs:
See documentation in the sources of the run time mentioned in paragraph
@strong{53}
I am not sure how to handle that without paragraph numbers,
maybe like this:
See documentation in the sources of the run time mentioned in the previous
paragraph.
[Bug c++/61506] ICE [4.10 Regression] triggered by solution to #61446
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61506 --- Comment #2 from Jürgen Reuter juergen.reuter at desy dot de --- This is the remark what I got from Andy Buckley: Line 29 of PDF.cc is the end of the file, which suggests to me an unclosed scope or similar higher up. The reported errors are entirely from within Boost itself -- and there aren't even any direct Boost functions being called in that file, so I don't think this is an LHAPDF issue at all. What platform and Boost version are you using? I don't know how to track it down, but my guess is that the issue is with this development version of GCC going wrong with some of the fiddly code in Boost... the implementation of lexical_cast, by the looks of things. To simplify your GCC test, I suggest just writing a minimal source file using lexical_cast to convert between strings and a few numeric types; it really doesn't look like this has anything to do with LHAPDF. Hope this helps!

enabled was really only supposed to be used to enable or disable
alternatives according to the current subtarget, rather than enable
or disable them based on the current stage in the pass pipeline
or on whether the function is being compiled for size or speed.
I have an idea for handling the size/speed thing, but we need
to fix the ??? as well.

Probably because with a variadic template there could be additional arguments that haven't been explicitly specified and so need to be deduced. However, in this case the number of function arguments should tell the compiler the pack only contains one type, and therefore nothing more needs to be deduced.

That's the preferred way in C, where at least one initializer is needed, but not in C++. If I understand you correctly, a better/cleaner way which achieves the exact same is using the cases of addr2 and addr6. Yes. Then I would rephrase my original statement and suggest that no warning will be issued for cases of addr2, addr6 and addr9. I agree with that suggestion.
