Hello,
This is a simple question for you all, I guess .
int main(){
double *g= new double;
*g = 9;
delete g;
cout<< sizeof(g)<<" "<<sizeof(double)<<" "<<sizeof(*g)<<" "<<*g<<" "<<endl;
*g = 111;
cout<< sizeof(g)<<" "<<sizeof(double)<<" "<<sizeof(*g)<<" "<<*g<<" "<<endl;

why not to build
a malloc_m() and a free_m() that *check* (if memory_debug=1) if
1) there are some errors in bounds of *all* allocated arrays
from them (and trace-print the path of code that make
the error and exit) just when malloc_m and free_m start.
(I use a 1100 static array for write the path (like a queue)
of called function, operator, etc and write using '+' where is
find the memory error)
2) if the pointer to free is alredy...

Dear all,
I happen to come across this exciting inspiring article regarding
memory leaks in this website:
http://www.embedded.com/story/OEG20020222S0026
In this article the author mentions:
"At a certain point in the code you may be unsure if a particular
block is no longer needed. If you free() this piece of memory, but
continue to access it (probably via a second pointer to the same

Hi,
My C code (running on Soalris Unix) has some "segmentation fault"
that I wish to use purify to do it. I poked around the web, and found
some information about adding some lines in a Makefile file to use
purify. However, my code is a rather simple single-source C program,
and I didn't write a Makefile for it.
I'm wondering if anybody can tell me which commands are to be
entered at the Unix prompt to use purify. And, I don't know if...

Hi,
I am new to C and having problems with the following program.
Basically I am trying to read some files, loading data structures into
memory for latter searching.
I am trying to use structres and arrays of pointers to them.
I have gotten the program to compile with gcc on WinXP.
If the file i read doesnt have alot of records, it runs thru. But once
i add more, it dies. In this program i have 4 files setup to read. The

Hello,
I'm trying to track down a memory issue with a C++ application that
I'm working on:
In a nutshell, the resident memory usage of my program continues to
grow as the program runs. It starts off at a nice 4% of memory, then
slowly grows up to 50% and beyond. This translates to around 2 gigs
of physical memory, and that's really way more memory than this
program should be taking up.

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,...
