Comment (by pulkomandy):
So there must be dependancies in libbe.so or elsewhere that are not
satisfied, if going back that far (to beta1). Shame, I bet it would have
solved the memory leak and crashing, sigh.
Well, older versions not having the alpha mask code surely wouldn't hit a
bug in the alpha mask code. But they wouldn't work, either, because the
interface kit makes use of the feature. Makes sense, I guess...
Also, it doesn't help much to have mix-and-matched tests here, because
they are hard to reproduce and quite likely to add more problems than they
solve (I understand it could be useful for you to find a workable setup,
still).
So, what we have so far:
- Crashes always in the memory allocation code, which hints to a heap
corruption
- Crashes often in the AlphaMask code, which is mostly exercised by
WebPositive
- In all reports attached, there are a lot of "some BLocker" in
app_server, so the whole thing is under some stress (lots of open windows
or open tabs in Web+). It doesn't seem to happen in a generally idle
system.
It would be nice if we could reproduce this in a more predictible way,
maybe with a test app stressing the use of alpha masks?
