Wt

Hello Koen & Wim,

I have tried in 32-bit and the markers are correctly displayed in both debug and release builds.
So the problem only occurs in 64-bit (windows VS2005).

Could you please tell me if you can reproduce the problem ?

Best Regards
Christophe

Hi,

I have fetched today's git and the bug is still there : no markers in 64-bit release in the sinusoid chart demo

Best Regards
Christophe

Christophe,

I can't reproduce this because I don't have such compiler. Could you give me some extra information about the bug? Is it only the sinusoid demo that fails? Is it because it is a sinusoid? Is it because of the use of 'double' in boost::any? Does it help if you replace the double by an int (and multiply the sin() result by e.g. 100)? Any other thoughts?

Best regards,
Wim.

Wim,

I will do some testing on monday. I can already tell you the problem is not specific to the sinusoid demo. I have the same bug in my application's chart which also use boost::any (with floats instead of doubles) and i don't use the sin() function.

Hi,
I have done some testing and the results are very strange.

It works if i change the code of MarkerRenderIterator::newValue as follows :

  virtual void newValue(const WDataSeries& series, double x, double y,
            double stackY,
            const WModelIndex& xIndex,
            const WModelIndex& yIndex)
  {    
      std::cout << x << "\n";
    if (!Utils::isNaN(x) && !Utils::isNaN(y) && !marker_.isEmpty()) {

It also works if i change the code as follows :

  virtual void newValue(const WDataSeries& series, double x, double y,
            double stackY,
            const WModelIndex& xIndex,
            const WModelIndex& yIndex)
  {    
    if (/*!Utils::isNaN(x) && !Utils::isNaN(y) && */ !marker_.isEmpty()) {

I cannot spend more time trying to debug. It would be nice if you could investigate when you have a Windows 64-bit machine.

Christophe,

Thank you for pointing us in this direction. This looks like a weird bug in MSVC's optimizer? Does it work for you to modify Utils.h, around line 196 from:

inline bool isNaN(double d) {
  return !(d == d);
}

to

inline bool isNaN(double d) {
  return _isnan(d);
}

(you may need to include float.h)
If that works, I'll update Wt so that this bug goes away.

Regards,
Wim.

Great!

It works.

Thank you very much!

The fix is on its way to public git and the next release.

Wim.
