Re: Scigraphica-gtkextra digest, Vol 1 #401 - 1 msg

Hi,

   Today 15thNov04, I checked out gtkextra-2 from CVS.
  I built it on WindowsXP (MinGW port) for testing
testrealtime.exe as I did last time.  I observed that 
testrealtime.exe doesn't crash after 15-20mins as
previous CVS gtkextra-2 version. But still it has
memory leaks (Windows Task Manager shows :( .). 
But less memory leak compared to previous one. 
CPU usage is also decreased comparate to previous one.
But still, CPU usage is high on autoscroll graph.

   I think, this leak is occured due to improper
handling of SaveDC (gtk_plot_gdk_gsave ())& RestoreDC
(gtk_plot_gdk_grestore() ).
   Unfortunately, Valgrind is not available on windows
XP :(.  Does anybody know valgrind equivalent tool on
windows.

Here is captured output :
