Not that I know much about the internals of the objc runtime,
but this indicates a bug in wish and/or the objc runtime
(tickled *by* the geometry state line, but not in gitk itself).
Note that the corrupted autorelease pool page data:

>  should be 0xa1a1a1a1 0x4f545541 0x454c4552 0x21455341

suggests that the page was already released or something,
since the three words of "should be" spell out "otua eler !esa"
which is "autorelease!" with byte-swapping (the old NUXI
issue but expressed in 32 bits this time).
