Details:
I did get this message on stderr:
20170202 01:25:04 error gui/general: vertical_scrollbar [_vertical_scrollbar]
recalculate: Can't recalculate size, force a window layout phase.
wesnoth: /build/wesnoth/src/wesnoth/src/gui/widgets/grid.cpp:529: virtual void
gui2::tgrid::place(const gui2::tpoint&, const gui2::tpoint&): Assertion
`false' failed.
That's this line in the code:
https://github.com/wesnoth/wesnoth/blob/1.12/src/gui/widgets/grid.cpp#L529
The comment states that this shouldn't be possible... and somehow it is.
We can only reach that place if this conditional fails:
https://github.com/wesnoth/wesnoth/blob/1.12/src/gui/widgets/grid.cpp#L466
As for 1.13, there have been some work on this function, and this conditional
is not there anymore. I guess it did get refactored away, since, as the
comment states, we shouldn't have been able to fail it anyway... but somehow
it did.
But there has been as well other work on that function.
Reproduction steps:
Download War_of_the_Dragon campaign from the add-on server. (currently
v1.4.2)
Start the campaign, switch to debug mode, use :cl to skip to the 6th scenario,
use :inspect, click on events and there on the one only one which has an ID.
I guess it's the case with other events with ids in mainline, but i didn't
find a test case.
