Crash when rebuilding texture cache

[J805]

I just installed 3.84 on a windows 10 computer. After loading the NOAA RNC charts for California via "add directory", I turned on open GL and checked the box for "texture compression caching". Then I click on "rebuild texture cache" to speed the charts up and the program crashed with the error "opencpn.exe has stop working". Any idea why this is happening?


Thanks

Did you really install version 3.84? Or is that a typo.

According to his screenshot, it is 4.8.4

To the OP, have you enabled OpenGL?

Sorry, typo. I installed 4.84

Is it the RNC State of California chart alone? No other charts installed? Is it the latest chart from NOAA web site?

Could you try the following:
1) move to a point with no RNC charts visible
2) restart OpenCPN

3) build the cache.



It's something I've seen too. I have some patches but I'm not sure they fully solve this issue.

Yes. Just the RNC for California, freshly downloaded via the chart downloader within Opencpn on another computer, copied the folder to usb drive and loaded on a different computer which has no internet access. No other charts loaded.

To know why it crashed we need a backtrace from a debugger.. unfortunately difficult.

If you start opencpn again, and again rebuild the cache does it eventually complete and become usable?

I will give this a shot the next time I am down at the boat, thanks.

No, it crashes every single time I have tried to rebuild the cache. Ive deleted the charts, reinstalled them, uninstalled the program, reinstalled it, rebooted, etc. The crash happens consistently.

Can you narrow the crash down to a single chart file? Does it show the name of the chart it processes when it crashes?

Can you post your log file?

As soon as I click the rebuild cache button, it crashes. It does not even start processing through the charts as far as I can tell. I will grab the log file the next time I'm down on the boat.

I believe I have narrowed the crash down to a simple double delete of a pointer.

The gltexCache code is loaded with dangling pointers. There are many megabytes left dangling on the heap when the program exits. It needs some serious pointer cleanup.

With that said, is there something I should do within my install to fix this? Or does this require programming that will be fixed on a future build?


Thanks
