Just got my first BSOD in Win Xp

Out of curiosity, could a memory shortage *ever* cause a BSOD?
Low memory conditions can *theoretically* cause a BSOD, but, this is more a Win9x thing... What's more probable is that you're overheating your processor, or that increased memory use can be increasing the probability of using a bad memory section, but it's very hard to say without a minidump. As a suggestion, I'd run MemTest86[^]. Just burn the ISO into a CD and boot with it, it'll stress test your memory chips and list anything that is bad. My experience with it is that 50% of the BSODs are simply bad memory chips or mis-configured BIOSes. Sometimes, simply lowering the memory speed can make them work safely. I see dead pixels Yes, even I am blogging now!

Sorry, but a Firefox extension could *NEVER* cause a BSOD by itself. It's just user-mode code, and can't corrupt kernel memory or do something else that could cause a BSOD...
*never* is a pretty strong word, I would venture to say it is possible to write software that as a side effect causes a BSOD.

Could you please point me how to code something in userland that causes a BSOD? Besides bugs in privileged code or hardware problems, it's not possible for user code to induce a BSOD.

I was going to mention the bug that was sent around a few years ago that involved the using
printfwith control characters (backspaces) that caused Windows to crash. And this was a simple few-liner C/C++ application. However, the "besides bugs" caveat is quite wide - it covers pretty much all possible scenarios... One could easily argue that all crashes are due to bugs in privileged code. :) Peace! -=- James
If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

It was, purely because you mentioned Firefox and crashing in the same sentence - that SessionSaver plugin has saved me a load of grief in the past from FF crashes, so I thought I'd mention it. Cheers, Paul
Indeed, it is a brilliant extension :) regards, Paul Watson Ireland Colib and ilikecameras. K(arl) wrote: oh, and BTW, CHRISTIAN ISN'T A PARADOX, HE IS A TASMANIAN!

Google up "CSRSS Backspace bug" for more info. An example that would crash NT4 and (some?) Win2K systems is/was:
#include <stdio.h>
int main(int iArgC, char *pArgV[] )
{
while( true )
{
for( int iLoop = 0; iLoop < 5; iLoop++ )
{
printf( "\t\t\b\b\b" );
}
}
return( 0 );
}Peace! -=- James

No, but this could BSOD on Windows 2000: printf("CrashMe\t\t\b\b\b\b\b\b");
