Thanks! We will reproduce it, and if it is reproduced, we will plan to fix it.

Steps to reproduce are:

make clean ; ./configure CC=clang-17 ; make

or

make clean ; ./configure CC=gcc-13 CFLAGS="-Wstrict-prototypes" ; make

or

make clean ; ./configure CC=gcc-11 CFLAGS="-Wstrict-prototypes" ; make

or

make clean ; ./configure CC=gcc-17 CFLAGS="-Wstrict-prototypes" ; make

The issue will be fixed on the qatzip 1.3.1 version
