I finally figured out why one of my apps sometimes fails under
Win32 when it always works fine under Linux: Under Win32, the
pickle module only works with a subset of floating point
values. In particular the if you try to dump/load an infinity
or nan value, the load operation chokes:
Under Linux:

it passed the moderator's veto - and I did not expect or desire anything

that Internet Explorer 6 fails on the "zero width space" U+200B
Is this observation still valid? For which versions of MS Windows
does it apply? Does it depend on the encoding (charset)?
I have a test page in three encodings:...

int a;
memset( a, 0, sizeof(a) );
Does that guarantee all bits zero?

Hi, All
I am reading FAQ of this group. I have a question about this:
http://www.eskimo.com/~scs/C-faq/q7.31.html
It says:
"
p = malloc(m * n);
memset(p, 0, m * n);
The zero fill is all-bits-zero, and does not therefore guarantee useful null
pointer values (see section 5 of this list) or floating-point zero values.

Hello.
I've been reading some past discussions on the NULL vs. zero.
References are always made to systems or machienes that use values
other than zero to represent the NULL pointer.
Although not a practice I follow, there are no doubt millions of lines
of open source libraries and applications that do things like:
p = malloc(...);

Hello,
I am trying out a few methods with which to test of a given number is
practically zero. as an example, does the following test correctly if a
given number is zero within machine precision? I am trying out this
method to check for a practical zero in an algorithm I am implementing
in C++.

As far as I can tell, (x & -1) is nonzero if the integer x is
negative zero. So for signed types, x == 0 does not guarantee
(x & foo) == 0. Is that right? (Not that I expect to ever
encounter a non-two's-complement machine. Just wondering.)

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
