[Gambas-devel] someimage.Clear then someimage.Draw raises signal 11

[Kevin Fishburne]

The lines:

   bwater.Clear
   bwater.Draw(dwater, 0, 0, 12288, 12288, 0, 0, 96, 96)

nuke the app. This may be related to the repeated sig 11's I've been 
getting which I was unable to reproduce under valgrind:

I'm still getting those, even without the recent someimage.Clear. This 
time I was able to guess the cause and add a breakpoint to identify the 
offending line. Seems the image routines are a bit susceptible to 
crashes, probably trying to write to memory outside the variable 
declaration. I'm currently using gt.gui (gtk) and gb.image.

FYI, the .Clear was an attempt to erase the image, rather than 
reinitialize it to an undimensioned state. The alpha kept compounding 
itself and needed to be cleared. Maybe there's a better way, such as 
DrawRect...
