- Subject: Query user with gdb MI intepreter
Hi all
I have a problem with the current gdb that, run from an eclipse
front-end using MI interpreter, query the user with defaulted_query ()
to prompt him to "Quit this debugging session?" .
Is that a normal behavior or not ?
I thought that gdb should not query user when using MI mode, but I can
we wrong, that's my point.
Here is part of th back trace. As you will see, we have an assertion
that comes from a problem with the frame unwinder, but I want first to
make sure that this assertion can request for user interaction or no.
The command that leads to the assertion is a simple -exec-next
