My workstation is configured to write properly named core dumps to special dir. Today checking cde-9999 ebuild (could be find in bug #505542) I've find the following issue: >>> Source compiled. >>> Test phase [not enabled]: cde-base/cde-9999 >>> Install cde-9999 into /var/tmp/portage/cde-base/cde-9999/image/ category cde-base /usr/lib64/portage/bin/ebuild.sh: line 719: 10893 Segmentation fault (core dumped) ( if [[ -n ${PORTAGE_PIPE_FD} ]]; then eval "exec ${PORTAGE_PIPE_FD}>&-"; unset PORTAGE_PIPE_FD; fi; __ebuild_main ${EBUILD_SH_ARGS}; exit 0 ) * The ebuild phase 'install' has exited unexpectedly. This type of * behavior is known to be triggered by things such as failed variable * assignments (bug #190128) or bad substitution errors (bug #200313). * Normally, before exiting, bash should have displayed an error message * above. If bash did not produce an error message above, it's possible * that the ebuild has called `exit` when it should have called `die` * instead. This behavior may also be triggered by a corrupt bash binary or * a hardware problem such as memory or cpu malfunction. If the problem is * not reproducible or it appears to occur randomly, then it is likely to * be triggered by a hardware problem. If you suspect a hardware problem * then you should try some basic hardware diagnostics such as memtest. * Please do not report this as a bug unless it is consistently * reproducible and you are sure that your bash binary and hardware are * functioning properly. Core dump directory showed, previously (during build process) happened core dump: $ ls -l /tmp/cores -rw------- 1 portage portage 425984 сен 13 09:59 core_30953.exe-6.31748 -rw------- 1 root root 24002560 сен 13 10:10 core_ebuild.sh-11.10893 The first core is an upstream issue. But portage should not crash (with core dumping) on any error in build system. $ equery u sys-apps/portage … * Found these USE flags for sys-apps/portage-2.2.8-r1: U I - - build : !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used for creating build images and the first half of bootstrapping [make stage1] - - doc : Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally - - epydoc : Build html API documentation with epydoc. - + ipc : Use inter-process communication between portage and running ebuilds. + + linguas_ru : Russian locale - - python2 : Use python2 as Python interpreter. - - python3 : Use python3 as Python interpreter. + + python_targets_python2_7 : Build with Python 2.7 + + python_targets_python3_3 : Build with Python 3.3 - - xattr : Preserve extended attributes (filesystem-stored metadata) when installing files. Usually only required for hardened systems. $ equery u app-shells/bash … * Found these USE flags for app-shells/bash-4.2_p45: U I - - afs : Add OpenAFS support (distributed file system) - - bashlogger : Log ALL commands typed into bash; should ONLY be used in restricted environments such as honeypots - - examples : Install examples, usually source code - - mem-scramble : Build with custom malloc/free overwriting allocated/freed memory + + net : Enable /dev/tcp/host/port redirection + + nls : Add Native Language Support (using gettext - GNU locale utilities) - - plugins : Add support for loading builtins at runtime via 'enable' - + readline : Enable support for libreadline, a GNU line-editing library that almost everyone wants - - vanilla : Do not add extra patches which change default behaviour; DO NOT USE THIS ON A GLOBAL SCALE as the severity of the meaning changes drastically $ einfo Portage 2.2.8-r1 (default/linux/amd64/13.0, gcc-4.7.3, glibc-2.19-r1, 3.12.21-aufs-r1

(In reply to Jeroen Roovers from comment #1) > 3) Please post the gdb backtrace from that core file. $ gdb /bin/bash --core core_ebuild.sh-11.10893 GNU gdb (Gentoo 7.6.2 p1) 7.6.2 … For bug reporting instructions, please see: <http://bugs.gentoo.org/>... Reading symbols from /bin/bash...(no debugging symbols found)...done. warning: core file may not match specified executable file. [New LWP 10893] warning: Could not load shared library symbols for linux-vdso.so.1. Do you need "set solib-search-path" or "set sysroot"? Core was generated by `/bin/bash /usr/lib64/portage/bin/ebuild.sh install'. Program terminated with signal 11, Segmentation fault. #0 0x00007eff8a283a88 in mbrtowc () from /lib64/libc.so.6 (gdb) Is it enough or I should rebuild app-shells/bash (?) enabling debug USE and re-reproduce this core?
Intermediate SIGABRT crash during build process doesn't corresponds with ebuild.sh crash. I've seen it also at least after build of cde-2.2.2. This crash reproduces only with incorrect ebuild from https://505542.bugs.gentoo.org/attachment.cgi?id=384652

not sure what the expectation is here. any time you hit infinite recursion, you're going to crash. just don't do that ...
