Dear Maintainer, Building Nginx Unit from source results in a compilation error. I tried both Debian 11 and Debian Sid (12), and the bug is reproducible in Sid only. To reproduce the problem, install the following packages: git, build-essential, libpcre2-dev Then execute the following commands: git clone https://github.com/nginx/unit.git cd unit/ ./configure make You will see the following error: --- cc -c -pipe -fPIC -fvisibility=hidden -O -W -Wall -Wextra -Wno-unused-parameter -Wwrite-strings -Wmissing-prototypes -Werror -g -I src -I build \ \ \ -o build/src/nxt_thread.o \ -MMD -MF build/src/nxt_thread.dep -MT build/src/nxt_thread.o \ src/nxt_thread.c In file included from src/nxt_unix.h:187, from src/nxt_main.h:31, from src/nxt_thread.c:7: src/nxt_thread.c: In function ‘nxt_thread_trampoline’: src/nxt_thread.c:114:5: error: ‘__sigsetjmp’ accessing 200 bytes in a region of size 72 [-Werror=stringop-overflow=] 114 | pthread_cleanup_push(nxt_thread_time_cleanup, thr); | ^~~~~~~~~~~~~~~~~~~~ src/nxt_thread.c:114:5: note: referencing argument 1 of type ‘struct __jmp_buf_tag *’ /usr/include/pthread.h:734:12: note: in a call to function ‘__sigsetjmp’ 734 | extern int __sigsetjmp (struct __jmp_buf_tag *__env, int __savemask) __THROWNL; | ^~~~~~~~~~~ cc1: all warnings being treated as errors --- If you reverse the order of the includes <pthread.h> and <setjmp.h>, which are included in <src/nxt_unix.h> (in the nginx unit source code), the error disappears: On 12/8/21 22:37, Valentin V.
