Hi, dear developers.
I found follwing trouble on CVS snapshot of 2000/05/25.
problem is as follows.
drawable: with alpha and some region selected.
tools: smudge or dodge/burn.
Apply above tools using any types of brush
(image pipe, normal brush, editable brush, any type.)
of diameter larger than 32 pixels to a layer with alpha channel, when
some area is selected. The core application crashes immediately.
below is a gdb backtrace in case smudge tool with 33 pixels editable
brush.
