I might add that I have visited:
Tools/Options/Debugger/Language Exceptions

But it does not stop the IDE from breaking on the exception handler I
want to debug.
I need to stop the Lazarus debugger pop-up from triggering by the
exception and allow me to reach the exception handler instead.
How can this be accomplished?
Do you want it to "not stop at all"
Or do you want it to "stop in the except/finally block"?
If you want to get to the finally block, then you have to stop in the
except first, and then do single steps. That should take you there.
There is no way to stop directly in the finally/except block.
If you do not want to stop at all, then that is "Notify on Lazarus
Exceptions"
That is all exceptions by "raise ...".
Run errors are separate, so are Signals (SigSegV, Sig....). Signals can
afaik not be suppressed.
"Notify on Lazarus Exceptions" just prevents the notification, internally the
execution still stops, but is continued immediately.
If of course your code throws hundreds of exceptions, then that still is a slow
down.
There is no option to prevent this.
For the handling of exceptions see
components\lazdebuggergdbmi\gdbmidebugger.pp line 5531
procedure ProcessException;
nested in
function TGDBMIDebuggerCommandExecute.ProcessStopped
To prevent the internal stop in exceptions search the file for FExceptionBreak
You will find calls to
FExceptionBreak.SetByAddr
or
FExceptionBreak.SetBy....
FExceptionBreak.SetBoth
FExceptionBreak.SetAt...
Those need to be commented out.
