Confirm, same issue here as well
not only systemd related, happened here at the tinderbox too it started here at a hardened image where 2.24-r1 was installed, non-hardened images with sys-libs/glibc-2.24 are fine till now
I'm hitting this with glibc-2.25 as well. Using hardened gcc-6.3.0, it doesn't seem to matter if glibc-2.25 has hardened enabled or not; locale-gen still crashes. Running localedef in gdb results in a useless message: (gdb) run -i en_US -f UTF-8 en_US.UTF8 Starting program: /usr/bin/localedef -i en_US -f UTF-8 en_US.UTF8 Program terminated with signal SIGSEGV, Segmentation fault. The program no longer exists. With a core dump, also seemingly useless: Core was generated by `localedef -i en_US -f UTF-8 en_US.UTF8'. Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00007fc1b3254204 in __spawni_child (arguments=0x7ffc03a7abe0) at ../sysdeps/unix/sysv/linux/spawni.c:122 122 ../sysdeps/unix/sysv/linux/spawni.c: No such file or directory.

(In reply to Toralf Förster from comment #2) which patchset was working ? you can modify the 2.24 ebuild and change PATCH_VER to 1, 2, 3, 4, or 5. we used to carry a localedef patch related to PaX, but we dropped it starting with 2.23. so if 2.23 is working, i don't think that's related.
if you put -fstack-check=no in CFLAGS and recompile glibc do it fix it?
-fstack-check=no fixed it for me. (glibc-2.25, gcc-6.3.0, +hardened)
(In reply to Magnus Granberg from comment #5) > if you put -fstack-check=no in CFLAGS and recompile glibc do it fix it? confirmed
Confirmed with Hardened, gcc 5.3.0
*** Bug 604198 has been marked as a duplicate of this bug. ***
this is due to a rewrite in upstream of the posix spawn API. https://sourceware.org/git/?p=glibc.git;a=commit;h=9ff72da471a509a8c19791efe469f47fa6977410 when the child is created, a stack of just one page is allocated. the stack checking blows that limit pretty easily and we segfault. i'll discuss upstream the best route to take.

Looks like your patch landed upstream. Can we get that applied in Gentoo's ebuilds?
