[Gimp-developer] 'Select all'/Feather causes segfault in histogram code

["David Gowers (kampu)" <00ai99 gmail com>]

Hi,
Select all, or Feather, causes gimp-2.9 to segfault inside the histogram code.
Which of the two it is, varies. A bit of messing around invoking free
select tool, Select menu items, or sometimes just Magic Wand will
immediately cause a crash.

I'm getting the impression that something's tiles get lost (and don't
invoke an immediate error condition) at some point prior to the crash,
because on occasion when using the free select tool, GIMP suddenly
starts acting as if there is no selection, no matter what I do.

Here's a stack trace:

I'm refraining from posting this to bugzilla cause I have no idea
whether it's trivial, something already known that's gonna be fixed in
due course, or what. Which of those it looks like, I'd like to know
though.
