With my news script, NewsIt, there is a problem with "compiling" the news. For some reason PHP crashes with memory read errors. MSVC++ Debug reveals that it's an Access Violation. The error, before debug, is as follows:

php.exe - Application Error
The instruction at "0x77fc999b" referenced memory at "0x00b1d54d". The memory could not be "read".

When debug is entered it has this error message:
Unhandled exception in php.exe (NTDLL.DLL): 0xC0000005: Access Violation.

These are the five lines of ASM, starting with the problem line:
77FC999B   mov         cl,byte ptr [eax+5]
77FC999E   test        cl,1
77FC99A1   je          77FCAFF2
77FC99A7   mov         word ptr [eax+2],di
77FC99AB   cmp         di,80h

This happens before anything is written to the file. E-mail me for the script, because the function that builds the news is too large.

can you compile a debug build and paste the call stack here?

I get this issue on Win 2K using php 4.3 built Dec 27 2002 05:28:00. I'm using Apache Webserver 2.0.43.

Whenever I start Apache, or load one of the web pages I get the following:

"Application Error ...The memory Could not be read...
Do you wish to debug?

Visual Studio debugger says:
"Unahandled Exception in php.exe (NTDLL.DLL)0xC00000005:Access Violation"
