Hi,
I am observing unexpected behaviour, in the form of a corrupted class
member access, from a simple C++ program that accesses an attribute
declared in a virtual base class via a chain of virtual method calls.
To further complicate (or perhaps simplify) matters, some compilers
(GCC and MingW) produce the expected behaviour, while others (MSVS 7.1)
do not. I can only offer two explanations for my observations:
1. The Microsoft...

I am using DevC++ 4.0 lately, which uses Mingw port of GCC, on a
WinXP. I am surprised to see the malloc behaviour which is not
consistent with the documentation. See the program and its output
below.
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv)

In C# (and C++/cli) the destructor will be called even if an exception
is thrown in the constructor. IMHO, this is unexpected behavior that can
lead to an invalid system state. So beware!

I came across this unexpected behaviour of getattr for new style classes.
Example:
>>> class Parrot(object):
.... thing =
....
>>> getattr(Parrot, "thing") is Parrot.thing
True
>>> getattr(Parrot, "__dict__") is Parrot.__dict__
False

Hi,
I am using gcc v4.0.2 on fedora core 4 (2.6.16). Any reason why the
handler set thru' set_unexpected() never gets called in the following
code?
--------- Code -------------

This regexp
'<widget class=".*" id=".*">'
works well with 'grep' for matching lines of the kind
<widget class="GtkWindow" id="window1">
on a XML .glade file
However that's not true for the re module in python, since this one
takes the regexp as if were specified this way: '^<widget class=".*"

I have a bunch of csv files that have the following characteristics:
- field delimiter is a comma
- all fields quoted with double quotes
- lines terminated by a *space* followed by a newline
What surprised me was that the csv reader included the trailing space in
the final field value returned, even though it is outside of the quotes.

hi to all!
after two days debugging my code, i've come to the point that the
problem was caused by an unexpected behaviour of python. or by lack of
some information about the program, of course! i've stripped down the
code to reproduce the problem:
<code>
a = {}
for x in range(10):

HTMLParser is behaving in, what I find to be, strange ways and I would
like to better understand what it is doing and why.
First, it doesn't appear to translate HTML escape characters. I don't
know the actual terminology but things like & don't get translated into

properly, it seems to omit it altogether! This prevents me from even doing

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
