[Posted to zsh-workers, with a Cc to the Debian bug.] While looking at Debian bug 993843
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=993843 (zsh-static segfaults immediately) I can notice the following warnings: gcc -static -o zsh main.o `cat stamp-modobjs` -lgdbm -lpcre -lcap -lncursesw -ltinfo -ltinfo -lrt -lm -lc /usr/bin/ld: options.o: in function `dosetopt': ./obj-static/Src/../../Src/options.c:830: warning: Using 'initgroups' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/bin/ld: Modules/parameter.o: in function `get_all_groups': ./obj-static/Src/Modules/../../../Src/Modules/parameter.c:2058: warning: Using 'getgrgid' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/bin/ld: Modules/files.o: in function `bin_chown': ./obj-static/Src/Modules/../../../Src/Modules/files.c:763: warning: Using 'getgrnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/bin/ld: params.o: in function `usernamesetfn': ./obj-static/Src/../../Src/params.c:4420: warning: Using 'getpwnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/bin/ld: options.o: in function `dosetopt': ./obj-static/Src/../../Src/options.c:822: warning: Using 'getpwuid' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking This is exactly the issue we are seeing in Debian: zsh-static segfaults after upgrading glibc, and this issue disappears after rebuilding zsh-static with the new glibc. And I could see in the strace output that the shared C library libc.so.6 is read, while zsh-static should entirely be static. However, --disable-dynamic-nss is used to build zsh-static, so that the above functions should not be called. I can see that Src/zsh_system.h has #if defined(HAVE_INITGROUPS) && !defined(DISABLE_DYNAMIC_NSS) # define USE_INITGROUPS #endif #if defined(HAVE_GETGRGID) && !defined(DISABLE_DYNAMIC_NSS) # define USE_GETGRGID #endif #if defined(HAVE_GETGRNAM) && !defined(DISABLE_DYNAMIC_NSS) # define USE_GETGRNAM #endif #if defined(HAVE_GETPWENT) && !defined(DISABLE_DYNAMIC_NSS) # define USE_GETPWENT #endif #if defined(HAVE_GETPWNAM) && !defined(DISABLE_DYNAMIC_NSS) # define USE_GETPWNAM #endif #if defined(HAVE_GETPWUID) && !defined(DISABLE_DYNAMIC_NSS) # define USE_GETPWUID #endif But concerning the first warning, Src/options.c contains # ifdef HAVE_INITGROUPS I suppose that the test should have been # ifdef USE_INITGROUPS like in Src/params.c, which has # ifdef USE_INITGROUPS initgroups(x, pswd->pw_gid); # endif I suspect that there is the same issue with the other warnings. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
