Hi,<br />
<br />
&nbsp; I am using MSVC 5.0 and it is a Win32 console application. My program always got a page fault when it runs a while. After tracing the error, I finally find that it occurs when I call free(). However, this is very strange because this free() call is within a loop. It looks like this:<br />
<br />
for(i=0;i&lt;48;i++) &nbsp;<br />
&nbsp; free(myPointer[i]); &nbsp;// error occurs when i=18<br />
free(myPointer);<br />
<br />
The error occured when i = 18! I have checked myPointer's dimension and I am sure memory was successfully allocated to it. I would like to know what is the probable cause for this problem, or is it a bug of VC?<br />
<br />
Any help is appreciated.<br />

page fault when call free()

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
