This seems to hang forever:

 $ LC_ALL=C info python3.10 -n 'Other Language Changes<3>'

[...]

Worse, when I change the terminal size while it's running, it segfaults.
Backtrace:

 #0  0x5661ca96 in window_make_modeline (window=window@entry=0x582a0b30) at 
./info/window.c:904

The crash-on-resize is not fixed, is it? Just more difficult to stumble upon?

I wrote a program to vigorously resize the terminal:

And indeed it makes info crash almost immediately.
