[Pkg-zsh-devel] Bug#759870: gcc-4.9: Compiles zsh endlessly on s390x (maybe sigjmp_buf related)

[Axel Beckert]

Package: gcc-4.9
Version: 4.9.1-9
Severity: serious
Affects: src:zsh

Dear GCC Maintainers,

since 2014-08-18 all zsh builds -- sid binNMUs as well as experimental
uploads -- fail on s390x upon the first gcc invocation by being killed
after 150 minutes of inactivity. Previous builds always took less than
15, sometimes just 5 minutes. See

  https://buildd.debian.org/status/logs.php?pkg=zsh&arch=s390x

One example:

  make[3]: Entering directory '/«PKGBUILDDIR»/obj/Src'
  gcc -c -I. -I../Src -I../../Src -I../../Src/Zle -I../../Src -D_FORTIFY_SOURCE=2  -DHAVE_CONFIG_H -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -Wall -g  -o builtin.o ../../Src/builtin.c
  E: Caught signal ‘Terminated’: terminating immediately
  make[3]: *** [builtin.o] Terminated
  make[2]: *** [modobjs] Terminated
  make[1]: *** [all] Terminated
  make: *** [build-arch] Terminated
  Makemod:231: recipe for target 'builtin.o' failed
  Makefile:451: recipe for target 'modobjs' failed
  Makefile:189: recipe for target 'all' failed
  debian/rules:48: recipe for target 'build-arch' failed
  Build killed with signal TERM after 150 minutes of inactivity

Waldi suspects some breakage related to the sigjmp_buf ABI issue. At
least zsh uses sigjmp_buf. Waldi also said on IRC he can reproduce the
issue.

                         Kind regards, Axel
