Debugging hangs while try to press step-in step-out (F10-F11

General JUCE discussion
1

Hi all,

I try to debug simple example, HelloWorld.
[ \extras\example projects\Builds\VisualStudio2008 ]

I open HelloWorld solution in Visual Studio 2010 Service Pack 1,
set Win32-configuration (debug),
open MainComponent.cpp,
and set breakpoint at:

//==============================================================================
void MainComponent::paint (Graphics& g)
{
//[UserPrePaint] Add your own custom painting code here…
//[/UserPrePaint]

------->>> here breakpoint <<- g.fillAll (Colour (0xffc1d0ff));

g.setColour (Colours::white);
g.fillPath (internalPath1);
g.setColour (Colour (0xff6f6f6f));
g.strokePath (internalPath1, PathStrokeType (5.2000f));

//[UserPaint] Add your own custom painting code here..
//[/UserPaint]

}

Next, when breakpoint occured, I press F11 (or F10) on breakpoint line "g.fillAll"
and Visual Studio was paused [hang up] and in command Window was writed:
first-chance exception in “0x03acf66f” in “HelloWorld.exe”: 0xC0000005: Access violation.

MS VS2010 SP1 paused and HelloWorld still paused [hang up] too while I cant press “stop debugging”.

In other way, when I set Win64-configuration, debugging in this place works fine.

In other places all works OK.

But in function:
"void MainComponent::paint (Graphics& g)"
Anywhere any breakpoints cant debug into or step-out.

Is it JUCE bug or Visual Studio 2010 bug ?

Bye,
Roman

I don’t know about vs 2010 but sometimes the vs 2008 debugger hangs the whole IDE when you try to step. It usually happens at the worst possible time (i.e. when debugging something that is challenging or hard to reproduce). So I would not be surprised if there is a bug in visual studio.

PS: In Win64 configuration all debugging in any places works fine.

If you don’t want to get warnings about your leaked objects, I generally find the best strategy is not to leak any objects.

I simply will not understand, where an error - in VS2010 without SP1 or in Visual Studio 2010 with Service Pack 1.

Debugging in void MainComponent::paint (Graphics& g)
dont work - dont work even in disassembly, step-by-step-command.

Try Visual Studio 2008

Hi again,
I found where is a problem.
When I disable “Enable RPC-debugging” in Tools->Options->Debugging->Machine code,
all debugging works fine.
Also was gone the message on an exception “first-chance exception”.
