How to set gdb's setting "BreakOnThrow" to true?

[grayfox]

When debugging with gdb, it won't break on throw, from the debugger log, I can see that the settings BreakOnThrow is defaults to off, so the question is, how can I turn it on?

I tried to specify "BreakOnThrow=true" on the gdb debugger settings but it doesn't work.

I am using Qt Creator 2.5.2 on Windows 7, with Qt 4.8.2 Mingw

Thanks

and you're asking that in a Qt programming forum because...?
