FYI I tested compilation with clang 14.0.6 on Debian bookworm (stable) podman
container and everything works as expected:

$ make cve-2015-3290 V=1; echo $?
removed 'cve-2015-3290'
clang -D_FORTIFY_SOURCE=2 -I../../include -I../../include -I../../include/old/ -g -O2 -g -O2 -fno-strict-aliasing -pipe -Wall -W -Wold-style-definition -std=gnu99 -D_GNU_SOURCE -pthread -fomit-frame-pointer -L../../lib cve-2015-3290.c  -lltp -o cve-2015-3290
0

Kind regards,
Petr
