In this case IrfanView always dies doing the same thing, and a failing memory would cause crashes more at random, depending on how the code and data are mapped to real memory. And if the same failing memory is used by other software I doubt they will survive for long. Flip one bit in a pointer (or in any address in your return stack) and you are likely to address something that isn't in your allocated memory space. This said, although IrfanView is photo-related, this topic would have been better suited to one of the comp.* groups. -- Bertrand |

Or not, as the case may be. And if the same failing memory is used by other software I doubt they will survive for long. Flip one bit in a pointer (or in any address in your return stack) and you are likely to address something that isn't in your allocated memory space. Depends on what specifically is happening. Generalizing that "this is the only program that shows identifiable symptoms therefore the problem cannot be hardware" is simply wrong-headed.

Problems w Irfanview ? It disappears.
"Crash!" wrote in message
om... Supposedly this is not Irfanview's fault, it's my system, so I wonder if anybody else has had it? The way I most often use Irfan is: I'll paste an image from Clipboard over an Irfanview image that came from any handy file icon. I'll edit that image, often cropping, cutting, pasting, adding text, sharpening and reduce color depth. I go to Save As, and the Irfanview window disappears. Gone. All lost. It seems worse after heavy editing, and worse in Save As than Save. It might happen about 1/3 of the time that I save after editing. Anybody else had that problem? Thanks! ====================== Have you uninstalled it, rebooted and installed it again? -- N |

I'd have agreed with that in the 70s, maybe even the 80s. But not these days, unless the software does something very hardware-specific, like using a specific peripheral or a common component in a very specific way (video card) but it doesn't seem to be the case here. -- Bertrand |

On very recent machines I've seen such problems go away when memory was replaced. The notion that a virtual memory system always puts things in different places is a gross oversimplification. |

Flip one bit in a pointer (or in any address in your return stack) and you are likely to address something that isn't in your allocated memory space. Do your programs consist mostly of pointers instead of doing real work or having real data? Memtest86 ist the right tool, just in case, and it should be run overnight. This will find memory problems or exclude them from the list of problems. -Wolfgang |

It needs a regular nap (reboot) every so often. It also needs to regularly get a good rest (full shutdown and reboot). There are several reasons why it will throw a temper tantrum. And, of course, like a child, there doesn't HAVE to be a reason, just if it feels like it. |

I remember running a memory tester on a machine for three weeks once and then the first time the application ran it gave the same parity error it always gave on that machine. Sometimes memory errors are prior-state-dependent and a test program can't always find those. |
