WG: [Kst] Debugging session kst Windows

Fri Nov 13 08:48:26 CET 2009

Hi again,

here the second kst-on-windows related message. It is the lof of a debugging session a colleague of mine performed. He's after a memleak which I am not sure is also there on Linux, but he's fairly new to Windows development so maybe there are more efficient tools (like valgrind on Linux) for this job than waiting for the application to crash and analysing a backtrace?

There again we'de appreciate any help.

Thanks, 

Nicolas

Betreff: [Kst] Debugging session kst Windows

Hi,

my colleague Grégoire has done a debugging session with kst 2 Windows and Microsoft tools to try and track the memleak that he is seeing, which is quite penalizing as kst crashes regularly. Please find attached the log. It is awfully long, but there may be interesting infos in there so I'm sending it unabridged. It seems that QPainter is not all that happy with what is happening. Note that in the middle of the file, he changes from using OpenGL to not using it and it looks a bit different. That happens at line 17265...

That problem and the slowness of the ASCII data source are currently the biggest issues we have on Windows. Hopefully we can track them down and solve them quickly. Is there actually any dev familiar with Windows listening on this list? We'd like to hear your advice, as I believe most of us are quite new to Windows development...

Nicolas
