Hi all,
Have a big big problem. app_server (under R5) gets into debugger and
while I understand the reason, I can't I find out why this happens.
I have attached 3 files to this mail. The archive has 2 pictures of
which I'll talk in a moment, then there's the test program and a stack
crawl.
What happens is, as you can see in Screen1.tga, 'this' pointer is NULL.
'this' should've pointed to "RootLayer 1". This is VERY strange as, in
the previous call, Layer::move_layer(), 'fParent' is valid!
I've spent several hours in solving this problem but had no success.
If you please have some time to look into this, it's much appreciated.
Thanks!
Now, how to reproduce:
- take main.cpp and link against our libbe.so (I use R5, so
libopenbeos.so)
- run the server, run the app.
- move (quickly) the floating window around.
(if you are not able to reproduce this, I will submit the WIP that I
have related to input stuff, and when this is enabled by a define in
Layer.h, it crashes a lot more often)
NOTE: I'm using GeekGadgets' compiler. (never had a problem with it)
Thank you!
Adi.
