Double clicking previous render in the VFB history crashes Houdini

[Muhammed_Hamed]

Hi

Test scene here,
https://drive.google.com/file/d/1j_U...ew?usp=sharing


Steps to produce the crash
-You will need to setup VFB history and do a quick test render to have something saved there, for example enable material override under options and set mode to lighting(just to have a quick fast render, as resolution is quite massive), now go to sampler tab and change noise threshold to .02 and do a production render
-After render is finished, click the save icon in the VFB, Now you will need to clear the frame buffer using this icon



-Now lets draw a render region and hit the play button



-Now you will need to stop the IPR, and then from the history panel click the one render you saved before



-Result, Houdini crashes without showing any messages
I recorded a video here of the process,

HI Muhammed_Hamed , I can't reproduce this on my side. Is this happen with every scene or with a new history directory, with only few saved images? Or with smaller image resolutions?

[Muhammed_Hamed]

it happens with every scene, and any saved renders
Can I upload to you my render, so you put to your history directory?
Maybe this can help your reproduce the issue

And thanks for all your help, cheers!

I think it's not needed, I'll just copy one big image a lot of times and will test it.

I really can't reproduce this crash even with more than a 100 4k images in the history directory.

I also could not reproduce this. Then I noticed your Task Manager in the video above - memory is 90+% full so I filled my PC's memory as well. Managed to get a crash following the same steps but before I log it, could you please verify the frame buffer is *not* crashing if you have some spare memory?

Thanks!

Hi Gosho.Genchev
Yeah, it is definitely the case here.. I didn't realize I'm out of memory then, and I'm glad I recorded the video..
I don't get that crash if I don't run out of memory on same machine(laptop), and I cannot reproduce on my main machine, that has 128 GB of RAM

Thanks for your help!
And thanks to Georgy as well

Best,
Muhammed

Awesome, thank you for verifying that was the case.

I'll log it, hopefully something can be done about the crash.

All the best!
