It looks fine. Does it because of x86 code is not supported to print out stack trace on x64?

What is the function of Handled or Not Handled in Event Filter dialog?

(I always set Execution option, but ignore the Continue option before.)

• Enabled : "When this exception occurs, the target immediately breaks into the debugger. This break in occurs before any other error handlers are activated. This method is called first-chance handling."
• Disabled : "The debugger does not break in for this kind of first-chance exception (although a message is displayed). If other error handlers cannot address this exception, execution stops and the target break into the debugger. This method is called second-chance handling."
• Notify : "When this exception occurs, the target application does not break into the debugger at all. However, a message is displayed that informs the user of this exception."
• Ignore : "When this exception occurs, the target application does not break into the debugger, and no message is displayed."

• Handled : "The event is considered handled when execution resumes."
• Not Handled : "The event is considered not handled when execution resumes."
