Public bug reported: posix_spawn usage in gnu make causes failures on s390x
Recently in gnu-make v4.3 https://paste.ubuntu.com/p/tYhbJFKN76/ it started to use posix_spawn, instead of fork()/exec(). This has caused failure of an unrelated package flatpak-builder autopkgtests on s390x only, like so echo Building make: echo: Operation not permitted make: *** [Makefile:2: all] Error 127 Julian Klaude investigated this in-depth. His earlier research also indicated that this is a heisenbug, if one tries to print to stderr before printing to stdout, no issue occurs. We are configuring GNU make to be build with --disable-posix-spawn on s390x only. We passed these details to Debian https://bugs.debian.org /cgi-bin/bugreport.cgi?bug=964541 too. But I do wonder, if there is something different or incorrect about posix_spawn() implementation in either glibc, or linux kernel, on s390x. Or gnu-make's usage of posix_spawn(). As otherise, using posix_spawn() in gnu-make works on other architectures, and flatpak-builder autopkgtests pass too. It seems very weird that stdout does not appear to be functional, unless stderr was opened/written to, from gnu-make execution compiled with posix-spawn feature. ** Affects: ubuntu-z-systems Importance: Medium Status: New ** Affects: glibc (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: make-dfsg (Ubuntu) Importance: Undecided Status: New ** Tags: reverse-proxy-bugzilla s390x ** Also affects: glibc (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886814 Title: posix_spawn usage in gnu make causes failures on s390x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1886814/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
