PHP is crashing with the following error:

The instruction at "0x77fcb03d" referenced memory at "0x00000000".  The memory could not be written.

The error occurs when I am accessing data from an array returned from mssql_fetch_array().

Sample code:

while($objArr = mssql_fetch_array($objRS))
{
print('This one works:'.nl2br(stripslashes($objArr['field1'])).'<br>');
print('Crashes here (sometimes):<br>'.nl2br(stripslashes($objArr['field2'])).'<br>');
}

The crash does not always occur. I believe it may depend on the data, but I can't find any correlation between the data in the database and when it crashes.

I cannot generate this crash on 4.1.x, but I can with 4.2.0 and 4.2.1.

Here's the point at which it crashes in the php4ts.dll:

-> 1008D772   jmp         1008D781

which jumps to this line:
1008D781   mov         esi,eax

Additionally, I DO NOT have magic quotes turned on, so I don't think that is the problem (see BUG #17497).

Please shorten your example to bare minimum which still
crashes and make it complete script.. And also try the latest (NON-stable!) snapshot from http://snaps.php.net/ 

With that script the bug _might_ be in nl2br() / stripslashes() / mssql_fetch_array()..

The latest STABLE (4.2.2-dev) snapshot took care of my problem. Thanks.

Closed then..
