Doesn't happen here. What is your default face's font with that theme?

I don't understand: if ascent=descent=1 and height=11, then how come
the condition
eassert (ascent >= 0 && ascent <= height);
fails to be true?
The backtrace tells a different story:
> #1 0x0000555555823630 in die
> (msg=0x555555991b70 "ascent >= 0 && ascent <= height",

> at xdisp.c:30993
It says here that height = 2 and ascent = 11. Which is very strange.
Can you tell what happens here (line 23325):
const int stretch_ascent = (((it->ascent + it->descent)
* FONT_BASE (font)) / FONT_HEIGHT
(font));
What are the values of the following at that line:
FONT_BASE (font)
FONT_HEIGHT (font)
it->ascent
it->descent
stretch_ascent
