fatal error: unhandled exception (During Bump Maps)

[Gimphried]

Hello eepjr24

In order to diagnostic the memory issue:

1. restart Gimp before each very big bumpmapping
   
2. make a clean reboot as you wrote yourself
   
3. Gimp menu Windows > Dockable Dialogs > Dashboard as suggested by rich2005
   
4. Gimp menu Windows > Dockable Dialogs > Error Console
   

How to run Gimp for debugging purpose?

Right-click Windows Start > contextually menu Windows Powershell.

Add or not the following Command Line Arguments after the Gimp executable as optional parameters:

Code:

. "C:\Program Files\GIMP 2\bin\gimp-2.10.exe" --console-messages --stack-trace-mode=always --no-shm

  ^ Don't forget the Powershell dot operator at the very beginning of the command. 

More precisely, use or not, --step-by-step--, the following Command Line Arguments:

• --console-messages: Do not popup dialog boxes on errors or warnings. Print the messages on the console instead.
  
• --stack-trace-mode=always: Debug in case of a crash
  
• --no-shm: Do not use shared memory between GIMP and plugins
  
• --no-cpu-accel: Do not use special CPU acceleration functions. Useful for finding or disabling buggy accelerated hardware or functions.
  

Powershell starts a new black console that will display a lot of GECL warnings even when it works.
At the end of session, after you quit Gimp, you are invited to close the black console:

For example even if it is unrelated with the subject:

Code:
