Crashing on exception: NSImage: Insufficient memory to allocate pixel data buffer

Targets macOS
1

On MacOS 10.13 we get this error on some Macs out of hundreds where the program is installed

Crashing on exception: NSImage: Insufficient memory to allocate pixel data buffer of 10741248 bytes
(10741248 or other)

And there is nothing in the crash log that tells me where to look, no method name from my “8Gestion” app

Help :slight_smile:

2

a 32 bit run out of memory?

You could handle the exception.

3

How ? There is already an UnhandledException handler in the App objet, and it did not fire

4

You could use my Bug Reporter Kit
http://www.monkeybreadsoftware.de/xojo/Bugreporter/

5

or implement NSExceptionHandlerMBS yourself.

6

Ok I will try NSExceptionHandlerMBS, thanks

7

But… where to place it?

Each of my methods ends with “Exception” where I report the error and process what I can.
I have to replace all of them with this one:
Exception no NSExceptionMBS
and consider “n”?

8

Well, problem is that your app runs out of memory.
I don’t know why.

But NSExceptionHandlerMBS can maybe catch it, you can report it and app ends.

You can of course look for the memory leak and try to fix it.

9

Whoa! It looks like you may have found another bug with High Sierra as a quick glance at your report seems to suggest that it’s crashing when the view gets focus and it’s possibly attempting to update its internal cache.

10

And I’ll wager that it’s NOT failing on 10.12 or earlier Mac OS versions.

Like Sam says, there are serious issues in CoreGraphincs and teh video driver layer in 10.13.2.

The simplest solution to partially solve the problem of crashes is to check in the Informations of Finder the option “Open in low resolution” for my app: it is not beautiful, but the number of crashes decreases enormously …
