Something went flaky in the test suite: I reproduced the issue
on first try with sbuild + overlay in tmpfs, but on second try
the build time test suite passed.  In the first build log, I
noticed something spews the "malloc_consolidate(): unaligned
fastbin chunk detected":

	[…]
	ok 19 - $static window starts on line -25 after ->scroll_to 25
	ok 20 - $vextent->start is now 25 after ->scroll_to 25
	ok 21 - Display after $vextent->scroll_to 25
	ok 22 - $widget has refcount 1 at EOF
	1..22
	ok
	malloc_consolidate(): unaligned fastbin chunk detected
	t/02input-key.t ............. 
	ok 1 - start is 0 initially
	ok 2 - hextent start is 0 initially
	ok 3 - start moves down +1 after <Down>
	[…]

but it does not appear on the second log, where the build goes
through successfully:

	[…]
	ok 19 - $static window starts on line -25 after ->scroll_to 25
	ok 20 - $vextent->start is now 25 after ->scroll_to 25
	ok 21 - Display after $vextent->scroll_to 25
	ok 22 - $widget has refcount 1 at EOF
	1..22
	ok
	t/02input-key.t ............. 
	ok 1 - start is 0 initially
	ok 2 - hextent start is 0 initially
	ok 3 - start moves down +1 after <Down>
	[…]

That does not mean I have any ideas though.

Anyway, for information,
Have a nice day,  :)
