I'm not seeing this problem with the current 
(84863a1c4dc8cca8fb0f6f670f67779cdd2d543b) gnulib version on Fedora 35 
x86-64, which has GCC 11.3.1 20220421 (Red Hat 11.3.1-2).

Here's how I tried to reproduce the issue:

./gnulib-tool -h --create-testdir --dir foo vasnprintf
cd foo
./configure
make CFLAGS='-fanalyzer -Wanalyzer-mismatching-deallocation -O2' check

Does the above work for you? If so, how does it differ from what groff does?

The idea is to make the problem reproducible without dealing with groff 
or with whatever changes you made to groff. If that's not possible, I 
guess we'll need a copy of your groff source since it sounds like you've 
modified groff.
