Query regarding wxwidget crash

[Pranav Tank]

Hi Wx-group,

 

We have been facing a crash situation in wxwidget library whose top of call stack points to following code lines.

We are using 3.0.2 version of Wxwidget in our application.

There is unfortunately not enough information here to tell you what's
going on. Please read https://trac.wxwidgets.org/wiki/HowToSubmitTicket and
try, as explained there, reproduce the problem in a small example. If you
can't do this, at the very least please explain what does your
PHView::OnPaint() do, it's really impossible to say anything without
knowing what it is.

Good luck,
