Package: src:glibc Version: 2.22-1 Severity: important User: debian-bsd@lists.debian.org Usertags: kfreebsd X-Debbugs-Cc: debian-bsd@lists.debian.org Hi, glibc/2.22 has a major problem on kfreebsd-i386. It built on the buildds, but the compiled ld-2.22.so is broken as seen on buildd finzi: https://buildd.debian.org/status/fetch.php?pkg=mksh&arch=kfreebsd-i386&ver=52c-1&stamp=1457437296 | dpkg: error processing archive /var/cache/apt/archives/libc-bin_2.22-1_kfreebsd-i386.deb (--unpack): | subprocess dpkg-deb --control was killed by signal (Illegal instruction) | Errors were encountered while processing: | /var/cache/apt/archives/libc-bin_2.22-1_kfreebsd-i386.deb Upgrading libc0.1 breaks pretty much everything: | Core was generated by `ld-2.22.so'. | Program terminated with signal 4, Illegal instruction. | (gdb) bt full | #0 0x0100622b in ??

It can be allowed again by sysctl kern.elf32.nxstack=0, but it would be better if glibc didn't need this. I wonder why this issue wasn't seen on kfreebsd-amd64 since executable stacks are not allowed there either.
