Hi,
So I made the schoolboy error of installing 9.0 whist I had a fully functioning V8.09 
It often crashes when opening but eventually stays open after the 3rd attempt.
Worked for a day or so.
Currently crashing and closing every time I try to open the Place Symbols dialog.
Initially it processes the symbol library then the footprint library, it always fails and closes, no warnings, no errors, no logs.
3rd party symbols are a non starter.
Driving me mad.
Is any of this fixed in 9.01?
Thanks
You could try installing 9.0.1 RC1 and see if it fixes your crash. They have fixed a lot of bugs.
I’ve opened a issue for a crash I’m experiencing on 9.0.1 RC1 which causes it to crash in schematic editor every 5 mins. So it may/may not fix your issue, or make it worse 
What operating system are you using? If windows, you could enable crash reporting and then we could see what’s causing these crashes.
Hi,
Just had a look at the Event Viewer, Looks like at least one of the errors may be caused by KiCad using masses of memory
‘The following programs consumed the most virtual memory: kicad.exe (14000) consumed 2427666432 bytes, eeschema.exe (2204) consumed 2140237824 bytes.’
Another Error - I don’t claim to understand these but maybe they means something to you…

Do you have crash reporting enabled? If you do, or if you can, please enable it and let us know your reporting ID if any further crashes occur:
Hi James,
Thanks for the reply, the UID is 1453f60b-3e65-4f88-ad1e-5c8c432e30c6.
There has been a couple of crashes since I turned this on, I will create another in a moment as it is currently easily repeatable.
Thanks
Hi,
Another update.
The crash did not occur at the expected point this time.
It opened the first Schematic and appeared to be working as expected.
When I opened a second Schematic with the first in the background it crashed on Place Symbol, the crash was a little more dramatic in that it also crashed DWM and went to not responding, I had to manually close this time.
I only found one issue logged to that UID (KICAD-K15), and it’s an assertion failure, not a crash. Are you running a debug build?
Hi Jeff,
Thanks for replying.
I am running the standard stable version 9.0, Not sure what you mean by KICAD-K15?
I have spent the afternoon working through my ERC errors & warnings (noob) and there has been around 8 crashes today - by crash I mean the program has done one of two things, sudden close without warning or an “unhanded exception” that freezes up the entire machine and cannot then be closed without using task manager.
My save’s are working for the most part so not too drastic!
Thanks
Just to add, the current round of “crashing” happens when opening ERC after making an edit but before a save.
If I save and then re open and run ERC - no failure.
Can you share the project that is causing these crashes? We’ve got the details from the crash reporting for where it’s going wrong.
I observe the same issue on my system. If I don’t save before running the DRC , the program occasionally crashes, and all changes are lost forever. But if I save beforehand, everything works fine.
